Terms of Use

These Terms of Use (the "Terms") are a binding agreement between Cyber Software Joint Stock Company, which operates the LetsMetrix platform ("LetsMetrix", "we", "us"), and the person or entity that registers for or uses the Services ("you").

By creating an account, connecting an integration, generating an API key, or otherwise using the Services, you agree to these Terms. If you are agreeing on behalf of an entity, you represent that you have authority to bind it. If you do not agree, do not use the Services.

These Terms incorporate by reference, and together form the "Agreement": the Privacy Policy, the Data Processing Agreement (DPA), the sub-processor list published within the Privacy Policy, and any order form or plan you accept.

1. Definitions

"Services" - the LetsMetrix platform, dashboards, research and comparison tools, free tools, reports, APIs, webhooks, exports, documentation and support, at letsmetrix.com and its subdomains.

"Workspace" - the tenant environment for your account, including its members, settings, integrations and data.

"Integration" - a connection you authorise between your Workspace and a third-party platform, including Google Analytics 4 and the Shopify Partner API.

"Connection Credentials" - the secrets needed to run an Integration, including Google OAuth tokens and Shopify Partner organisation identifiers and access tokens.

"Connected Data" - data retrieved from a third-party platform using your Connection Credentials, at your instruction.

"Customer Data" - everything you submit to the Services or that we retrieve on your instruction, including account information, Connection Credentials and Connected Data.

"Public Market Data" - data we independently collect from publicly accessible sources, principally the Shopify App Store. "Derived Insights" - the estimates, scores, rankings, benchmarks and analyses we compute from it. "Output" - the reports, charts, exports and AI-generated content the Services produce for you.

"Usage Limit" - the thresholds applicable to your plan: seats, tracked apps, connected properties, API requests, AI credits, exports, history depth.

2. Account, licence and plans

2.1 You must be at least 18 and legally able to contract. You must provide accurate registration information and keep the email address on your account valid and monitored, because we deliver service, security, billing and legal notices to it.

2.2 You are responsible for all activity under your account, for the confidentiality of your credentials and any API keys you generate, and for your workspace members' compliance with the Agreement. Remove members promptly when they no longer need access - members may be able to view Connected Data. Notify us at [email protected] if you suspect unauthorised access.

2.3 Licence. Subject to your compliance and payment of fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable right to access and use the Services for your own internal business purposes during the Term.

2.4 Output. You may use and internally distribute Output within your organisation, and may include reasonable extracts in client deliverables, investor materials or public content provided you attribute LetsMetrix and do not present as verified fact anything labelled an estimate. You may not redistribute, resell, sublicense or publish Output in bulk, or in a way that substitutes for a subscription.

2.5 Plans and limits. Each plan has a feature set and Usage Limits stated at purchase. If you exceed a limit we may, with notice where practicable, require an upgrade, apply disclosed overage charges, throttle, or suspend the affected functionality. We will not delete your data solely because you exceeded a limit. Where your plan includes API or feed access, use the credentials issued to you, respect published rate limits, and do not share credentials outside your organisation. We may rate-limit or revoke API access that threatens Platform stability or that we reasonably believe is being used to replicate our dataset systematically.

2.6 Service evolution and availability. We may modify, add or discontinue features, but will not materially reduce the core functionality of a paid plan during a paid billing period without notice under Section 13. Beta features are provided "as is" and may be withdrawn at any time. The Services are provided on a commercially reasonable efforts basis; data freshness depends on third-party API availability and rate limits. Free plans and free tools carry no service commitment and may be changed or withdrawn at any time.

2.7 Competitor restriction. You may not use the Services to build, train or benchmark a competing product, or on behalf of a competitor, without our prior written consent.

3. Integrations and authorised connections

3.1 Voluntary. All Integrations are optional and opt-in. The Platform remains usable, with reduced functionality, without any Integration.

3.2 Your authorisation is our instruction. By connecting, you instruct us to access that platform on your behalf using the Connection Credentials you provide, and to retrieve, store, process and display the resulting Connected Data in your Workspace. We act on that instruction and no other.

3.3 Your representations. By connecting an Integration you represent and warrant that: (a) you own the connected account or are authorised by its owner to connect it; (b) doing so breaches no agreement with a third party, including the Google APIs Terms of Service and the Shopify Partner Program Agreement; (c) where the Connected Data includes personal data of your merchants, end users or personnel, you have a valid legal basis and have given all required notices and obtained all required consents; and (d) you will not connect an account containing data you are prohibited from sharing with a service provider.

3.4 Our commitments. In respect of Connection Credentials and Connected Data we commit that: (a) we request the narrowest scope necessary, read-only where read-only suffices; (b) credentials are stored encrypted in a store separate from our main database, never logged, never displayed back in full, and not accessible to our personnel in plaintext in the ordinary course; (c) Connected Data is logically isolated per Workspace and inaccessible to any other customer; (d) we do not sell, license or disclose it to anyone other than our listed sub-processors, and never for their own purposes; (e) we do not use it to train, fine-tune or improve any AI or machine-learning model, and it is never included in an AI prompt; and (f) we will not begin retrieving a materially new category of Connected Data without notifying you and, where required, obtaining fresh consent.

3.5 Estimate Calibration Programme. By default we do not use your Connected Data to build, calibrate, validate or benchmark the Public Market Data or Derived Insights shown to any other user. You may separately and voluntarily opt in to the Estimate Calibration Programme, which is off by default, enabled by a distinct control with its own consent screen, and never a condition of any other feature. Its safeguards - including the twenty-application cohort threshold, the rule that only aggregate coefficients and never your raw data leave your Workspace, the prohibition on calibrating your own listing with your own data, and your right to withdraw - are set out in Section 4.4 of the Privacy Policy and form part of the Agreement. Declining has no effect on your plan, price or support.

3.6 Google and Shopify terms. Our use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Your Google Analytics account remains governed by your agreement with Google, and your Partner account by your agreement with Shopify, including the Shopify Partner Program Agreement. You are solely responsible for compliance with those terms, including any restriction on disclosing merchant data to third parties.

3.7 Revocation and dependency. You may disconnect any Integration at any time; we revoke the credential upstream where supported and delete it within 24 hours, which may disable dependent features and historical views. Third-party platforms may change, deprecate, rate-limit or terminate their APIs without notice to us. We are not liable for the resulting loss of functionality, data gaps or delays, and such events do not entitle you to a refund, though we will use commercially reasonable efforts to restore or replace affected functionality.

4. Ownership

4.1 Your data. As between the parties, you retain all right, title and interest in Customer Data, including Connected Data. You grant us a non-exclusive, worldwide, royalty-free licence to host, store, transmit, process and display it solely to provide, secure and support the Services for you, and as permitted by the DPA. That licence ends when the data is deleted under Section 10.

4.2 Aggregated data. We may generate fully aggregated and irreversibly anonymised statistical and operational data that identifies neither you, your Workspace, your merchants, nor any individual, and use it to operate, secure and improve the Services. We will not attempt to re-identify it, and will not publish or commercialise any aggregate derived from Connected Data that could reasonably be attributed to an identifiable customer, except as expressly permitted under Section 3.5.

4.3 Our IP. We and our licensors own all right, title and interest in the Services, including software, models, methodologies, database structures, interfaces, documentation and trademarks. No rights are granted except those expressly stated. Do not remove or alter any proprietary notice. You may reference our name factually to describe your use of the Services; any other use requires written consent.

4.4 Feedback. If you send us ideas or suggestions we may use them without restriction or obligation. Feedback is voluntary and not confidential.

5. Market data, estimates and AI output

5.1 Nature of the data. Public Market Data comes from publicly accessible sources. Derived Insights are estimates produced by our models - not audited figures, and not data supplied to us by the developers concerned.

5.2 Estimates are estimates. Install counts, revenue, MRR, growth, churn, rankings and sentiment scores presented in the Services are modelled approximations that may differ materially from actual figures. You must not represent them as verified, actual or audited. You are solely responsible for any decision you base on them - including investment, acquisition, pricing, hiring or competitive decisions - and should verify material figures independently.

5.3 AI output. Certain features use artificial intelligence to summarise, classify or generate content. AI output may be inaccurate, incomplete or biased, and may state plausible things that are false. It is not legal, financial, investment, tax or professional advice. You are responsible for reviewing and verifying it before relying on or publishing it. AI output is generated probabilistically; other users may receive similar or identical output, and we make no representation that it is unique or protectable. AI features may consume plan credits, which are non-refundable and do not roll over unless stated.

5.4 Third-party rights. App names, logos, screenshots and review text shown in the Services belong to their owners and are displayed for identification, research and commentary. LetsMetrix is not affiliated with, endorsed by or sponsored by Shopify Inc., Google LLC, or any app developer profiled in the Services.

5.5 Accuracy claims. If you believe data about your app is inaccurate, write to [email protected] with the app identifier and the specific figures in dispute. We review within 10 business days, correct verified errors, and label disputed estimates.

6. Acceptable use

You shall not, and shall not permit anyone to:

(a) use the Services unlawfully, or in violation of the terms of Shopify, Google or any other connected platform; (b) scrape, crawl, harvest or systematically extract Public Market Data or Derived Insights other than through an API or export we provide for that purpose; (c) resell, redistribute, sublicense or make available our data in bulk, or use it to build or maintain a competing dataset or product; (d) reverse engineer, decompile or attempt to derive the source code, models or underlying methodology of the Services, except where this restriction is unenforceable by law; (e) resell, rent, lease, sublicense or time-share the Services, or operate a service bureau, except under a written agreement with us; (f) share account credentials or API keys outside your organisation, or circumvent Usage Limits or access controls, including by creating multiple accounts; (g) interfere with, overload or disrupt the Services, or probe or scan them without authorisation; (h) introduce malware, or attempt unauthorised access to the Services, other customers' Workspaces or our infrastructure; (i) upload unlawful, infringing, defamatory or malicious content; (j) use the data to harass, defame, dox or unlawfully target any developer, merchant, reviewer or individual; (k) use the Services to make automated decisions about individuals producing legal or similarly significant effects; or (l) connect an account you are not authorised to connect.

Breach of this Section is a material breach and may result in immediate suspension under Section 10.2. We may report unlawful activity to the relevant authorities.

7. Fees and payment

7.1 You agree to pay the fees for your plan at the prices displayed at purchase or set out in your order form. Payments are handled by our third-party payment processor; we do not store your full card details.

7.2 Renewal and cancellation. Subscriptions renew automatically until cancelled. You may cancel at any time in Workspace Settings, effective at the end of the then-current billing period.

7.3 Taxes. Fees exclude taxes unless stated. You are responsible for all applicable taxes, duties and withholdings other than taxes on our net income, and will gross up if withholding is legally required.

7.4 Price changes. We may change fees on at least 30 days' notice under Section 13, effective at the start of your next billing period. If you do not accept a change, cancel before it takes effect.

7.5 Refunds. Except where required by law, or where we terminate for convenience under Section 10.3, fees are non-refundable, including for partial periods, unused capacity, unconsumed credits and periods of non-use.

7.6 Late payment. If payment fails we may retry, suspend access after notice, and charge interest on overdue amounts at the lower of 1.5% per month or the maximum permitted by law. Fees accrued before suspension remain due.

7.7 Trials. Where disclosed at signup, free trials convert to a paid plan unless cancelled beforehand. We may modify or withdraw trial offers at any time.

8. Confidentiality

Each party may receive the other's non-public information - in your case your Customer Data and business plans, in ours our non-public roadmaps, pricing, methodologies and security documentation. The receiving party will protect it with at least reasonable care, use it only to perform under the Agreement, and disclose it only to personnel and advisers who need it and are bound by confidentiality. This does not cover information that is or becomes public without breach, was rightfully known beforehand, is independently developed, or is rightfully received from a third party without restriction. Disclosure compelled by law is permitted with prompt notice where legally allowed, limited to the minimum required. These obligations survive three years after termination, and indefinitely for personal data and trade secrets.

9. Data protection

9.1 Where we process personal data on your behalf - principally Connection Credentials and Connected Data - the DPA applies and is incorporated into these Terms, covering security, sub-processors, breach notification, assistance with data subject rights, audit and deletion. Where we process personal data as controller - principally account, usage and Public Market Data - the Privacy Policy applies.

9.2 You are solely responsible for the lawfulness of the data you connect or submit, for establishing a legal basis, for giving notices and obtaining consents from your merchants and end users, and for the lawfulness of your instructions to us.

9.3 Precedence for data matters. (i) mandatory provisions of applicable data protection law; (ii) the DPA; (iii) these Terms; (iv) the Privacy Policy. For all other matters, Section 13.7 applies.

10. Term, suspension and termination

10.1 Term. The Agreement starts when you first create an account or use the Services and continues until terminated.

10.2 Suspension. We may suspend access, in whole or part - with notice where practicable, without notice where the risk requires - if you materially breach the Agreement including Section 6; your use poses a security, legal or stability risk; payment is overdue after notice; or the law or a connected platform requires it. We restore access promptly once the cause is resolved.

10.3 Termination. You may terminate at any time by cancelling and closing your Workspace, effective at the end of the current billing period unless you request immediate closure. Either party may terminate immediately for a material breach not cured within 30 days of notice, or without a cure period for a breach of Section 6, a security risk, insolvency, or where the law requires. We may terminate a paid plan for convenience on 30 days' notice, refunding prepaid fees for the unused remainder of the current period.

10.4 Effect. Your access ends and accrued fees fall due. For 30 days after termination we keep your Workspace data retrievable and give reasonable assistance to export it in a structured, machine-readable format - except where termination followed a breach of Section 6 involving misuse of data or a security risk. Connection Credentials are deleted within 24 hours of disconnection or termination. Remaining Customer Data is deleted or irreversibly anonymised within 30 days after the export window closes, except where retention is legally required (for example billing records), in which case it is isolated from active processing and deleted at the end of the statutory period; encrypted backups purge at the next rotation, within 35 days. You may waive the export window and request immediate deletion.

10.5 Survival. Sections 1, 4, 5.2 - 5.4, 7 (accrued fees), 8, 9, 10.4, 11, 12 and 13 survive termination.

11. Disclaimers and limitation of liability

11.1 Disclaimers

EXCEPT AS EXPRESSLY STATED, THE SERVICES, OUTPUT, PUBLIC MARKET DATA AND DERIVED INSIGHTS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE AND NON-INFRINGEMENT.

We do not warrant that Public Market Data, Derived Insights, estimates, rankings or AI output are accurate, complete, current or fit for any particular decision; that the Services will be uninterrupted, secure or error-free; that use of the Services will improve any business metric; or that any third-party platform, API or source, including Shopify and Google, will remain available, accurate or continuous. Nothing in the Services is legal, financial, investment, tax, accounting or other professional advice. Where a jurisdiction does not allow these exclusions, they apply to the maximum extent permitted and no non-excludable statutory right is affected.

11.2 Limitation of liability

(a) Indirect damages. To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of profits, revenue, goodwill, business opportunity, anticipated savings or data, however caused, even if advised of the possibility.

(b) Reliance. We are not liable for any decision you make in reliance on Derived Insights, estimates or AI output, including investment, acquisition, divestment, pricing or competitive decisions.

(c) Caps. To the maximum extent permitted by law, each party's total aggregate liability arising out of or in connection with the Agreement, whether in contract, tort (including negligence), statute or otherwise, will not exceed:

Where more than one cap could apply to a single claim, the higher applies, and all caps are aggregate rather than cumulative across claims.

(d) Exclusions from the caps. These limits do not apply to: your payment obligations; your breach of Section 6; either party's indemnity obligations under Section 12; fraud, wilful misconduct or gross negligence; death or personal injury caused by negligence; or any liability that cannot lawfully be limited, including statutory liability under applicable data protection law.

(e) You acknowledge that the fees reflect this allocation of risk.

12. Indemnification

12.1 By you. You will defend and indemnify us and our officers, employees and agents against any third-party claim, and resulting loss, damage, liability, cost and reasonable legal fees, arising from: your breach of the Agreement; your Customer Data or instructions, including any claim that you lacked the right or legal basis to connect or disclose Connected Data; your violation of the terms of Shopify, Google or another connected platform; your use of Output; or your violation of any law or third-party right.

12.2 By us. We will defend you against any third-party claim that the Services, as provided by us and used in accordance with the Agreement, infringe that third party's intellectual property rights, and pay damages finally awarded or amounts we agree in settlement. This does not apply to claims arising from your Customer Data; third-party content within Public Market Data displayed for identification or commentary; modification of the Services by anyone but us; combination with anything not supplied by us; or use in breach of the Agreement. If such a claim arises or appears likely, we may procure the right to continue, modify the Services, or terminate the affected Service and refund prepaid unused fees. This states our entire liability for intellectual property infringement.

12.3 Procedure. The indemnified party will promptly notify the other, give it sole control of defence and settlement (no settlement imposing non-monetary obligations without consent), and cooperate reasonably at the indemnifying party's expense.

13. General

13.1 Changes. We may amend the Agreement. We give at least 30 days' advance notice of material changes - those substantially altering your rights, obligations, fees, our data-handling practices, or the core functionality of a paid plan - by email and prominent in-Platform notice, stating the effective date. Clarifications, formatting and typo corrections may be made without advance notice. Continued use after the effective date constitutes acceptance; if you do not accept, terminate before that date and we will refund prepaid fees pro rata for the unused remainder of the current period. Where you have signed a separate written agreement or order form, that document controls to the extent of conflict and we will not unilaterally amend its negotiated terms during its term.

13.2 Governing law and disputes. The Agreement is governed by the laws of Vietnam, without regard to conflict-of-law principles and excluding the UN Convention on Contracts for the International Sale of Goods. Before commencing proceedings the parties will attempt in good faith to resolve the dispute between senior representatives for 30 days after written notice. Unresolved disputes are subject to the exclusive jurisdiction of the competent courts of Vietnam. Either party may seek urgent injunctive relief in any competent court to protect its intellectual property or confidential information. If you use the Services as a consumer in a jurisdiction granting you mandatory local protections or a local forum, those rights are unaffected.

13.3 Notices. We give notice by email to your account contact or through the Platform. You give notice to [email protected] and, for termination or dispute notices, also to our registered address. Notice is deemed given on the next business day.

13.4 Assignment. You may not assign without our prior written consent, except to a successor to substantially all of your business that is not our competitor, on written notice. We may assign to an affiliate or in connection with a merger, acquisition or sale of assets.

13.5 Force majeure. Neither party is liable for failure or delay (other than payment) caused by events beyond its reasonable control, including natural disaster, war, civil unrest, epidemic, government action, internet or utility failure and third-party platform outage.

13.6 Miscellaneous. If any provision is unenforceable it is modified to the minimum extent necessary and the remainder continues. Failure to enforce is not a waiver. The parties are independent contractors; no partnership, agency or joint venture is created. No third party may enforce the Agreement except as expressly stated. You represent that you are not located in or a resident of a comprehensively sanctioned country, are not on a restricted-party list, and will comply with export control and sanctions laws. Each party will comply with applicable anti-bribery laws. We will not use your name or logo as a customer reference without your prior written consent, withdrawable on notice. The Agreement is drafted in English; any translation is for convenience and the English version prevails.

13.7 Entire agreement and precedence. The Agreement is the entire agreement on its subject matter and supersedes all prior discussions and versions of these Terms. For data protection matters, Section 9.3 applies. For all other matters: (i) a signed order form; (ii) these Terms; (iii) the DPA; (iv) the Privacy Policy; (v) documentation and plan descriptions.
