Compare Versions

Terms of Service

Last updated: 24 September 2026 · Version 2026-10-02

1. Agreement

This End-User License Agreement and Terms of Service (“Agreement”) governs your use of Compare Versions websites, applications, and related tools (collectively, “Services”) operated by Compare Versions (“we”, “us”, or “our”).

By creating an account, accessing, or using the Services, you agree to this Agreement. If you use the Services on behalf of a company or other entity, you represent that you have authority to bind that entity, and “you” includes that entity. If you do not agree, do not use the Services.

The Services are offered globally. Users may access Compare Versions from any country, subject to this Agreement and applicable local law.

2. Definitions

  • Online Service — any website, PDF, or other online resource accessible on the public internet or via credentials you supply.
  • Content — information (text, HTML, images, PDF-derived HTML, or other data) obtained from an Online Service through the Services or stored by you in the Services.
  • User Information — URLs, settings, snapshots, diffs, and other data you submit to the Services.

3. License

Subject to this Agreement and payment of applicable fees (if any), we grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Services for lawful webpage and document change monitoring as intended by the product.

We retain all rights in the Services, software, and documentation. No ownership is transferred to you.

4. Your responsibilities — monitoring & fetching

Compare Versions is a neutral software tool. We do not choose which Online Services you monitor. You direct the Services to fetch or process URLs and documents on your behalf.

By using the Services, you represent and warrant that:

  • You are legally permitted to access and monitor each Online Service you configure;
  • You have authorization from the site owner, your employer, or applicable law to collect and use Content for your purpose (e.g. compliance, your own published pages, or contracted partner monitoring);
  • Your use complies with all applicable laws, regulations, and third-party rights (including copyright and contract terms);
  • You will not use the Services to access login-protected areas without proper authorization or valid session credentials you are entitled to use.

Unless you have explicit authorization from the operator of an Online Service, you must respect reasonable access restrictions, including robots.txt directives, rate limits, and technical measures disclosed to you. If you bypass such restrictions, you represent that you have the necessary rights and consents to do so.

You agree not to use the Services to:

  • Violate applicable law or third-party rights;
  • Launch denial-of-service attacks or impose unreasonable load on Online Services;
  • Send spam, malware, or automated abuse unrelated to legitimate monitoring;
  • Scrape or resell third-party Content as a data product without rights to do so;
  • Reverse engineer, copy, or build a competing product from the Services;
  • Interfere with the security or operation of the Services or any Online Service;
  • Expect or require us to defeat access controls, verification steps, or other restrictions on Online Services without the necessary rights or consents.

5. Service scope

Compare Versions is intended for authorized change monitoring of public webpages — for example pricing or policy pages, product terms, help content, and similar published reference pages.

The Services:

  • Fetch Online Services using standard network requests and browser automation on our infrastructure;
  • May, where you are authorized to monitor the content and normal retrieval is unreliable, use additional operator-managed fetch paths (including routed egress through third-party proxy providers) solely to obtain the intended public page for change monitoring;
  • Are designed for authorized change-monitoring workflows rather than custom access-evasion techniques directed by end users;
  • May store challenge-style or blocked responses when that is the only content returned, so you can see that access failed rather than silently missing a change;
  • May download PDF documents and convert them to HTML for change comparison where conversion succeeds;
  • May limit monitoring, storage, or continued processing of URLs that do not return the intended content or otherwise cannot be retrieved reliably in the normal course of service operation;
  • May apply service-side handling rules where access conditions prevent reliable retrieval of the intended content.

PDF monitoring depends on successful download and conversion to a comparable HTML representation. Some PDFs (for example scanned images without extractable text, corrupted files, password-protected files, or formats our converters cannot process) may fail conversion or yield incomplete text — in those cases monitoring may be limited or unavailable for that document.

Some Online Services use access controls, bot checks, or delivery paths that prevent reliable automated retrieval of the intended content. Where that occurs, monitoring may be limited, unavailable, or require operator approval and a different service tier or implementation. On Scale and higher plans, we offer Proxy as a paid add-on. When you enable it for a URL, we may route that fetch through third-party residential proxy providers to obtain the intended page. Proxy is available only for Online Services you are authorized to monitor under section 4, and results are not guaranteed — some sites remain unavailable regardless of fetch path. On lower plans, or where we withdraw the add-on, proxy-assisted fetch is not included.

See our Pricing page for plan tiers and current scope.

5c. Proxy add-on

  • Proxy is billed as a separate subscription from URL monitoring. Cancelling one does not cancel the other.
  • Your slot count sets how many URLs may have Proxy on at once. It is not a promise to charge for every slot.
  • You pay only when Proxy succeeds, up to $1.50 per URL / month, billed in arrears via metered usage. Failed attempts are free for as long as Proxy stays on.
  • Proxy usage is billed in $0.50 increments. Any unused amount under $0.50 carries to your next billing period and is shown on Account → Billing when present. If you cancel the proxy add-on (or it expires), leftover under $0.50 is waived.
  • Proxy stays on until you turn it off, or until about 120 days with no successful fetch for that URL. Then we turn Proxy off and free the slot. You can turn it on again later if you have a free slot.
  • Add slots = immediate capacity, billed on cycle. Reduce is locked until next renewal (same model as URLs).
  • Fall below Scale → Proxy pauses; slots and settings are kept and resume if you return to Scale+.
  • Deleting a webpage frees its slot. Membership purge or account delete clears proxy settings and cancels the add-on.
  • Proxy does not guarantee retrieval on any given site.

5a. Freemium trial & data retention

We may offer a free time-limited tier (for example, up to ten (10) monitored URLs for thirty (30) days from registration) so you can evaluate the Services (“Freemium”).

When the Freemium period ends, unless you subscribe to a paid plan before or at expiry:

  • Scheduled monitoring and fetching for your URLs will stop;
  • We will delete or de-identify User Information associated with monitoring, including stored snapshots, versions, diffs, folders, and related monitoring configuration, subject to technical and backup retention limits described below;
  • We may retain your account identifier, email address, registration metadata, and records needed for security, billing disputes, and legal compliance. We may contact you about the Services for service and marketing purposes using your email address where permitted by law.

You are responsible for exporting or saving any information you need before Freemium expiry. Paid plans are subject to the retention limits shown on the Pricing page and your plan quotas.

5b. Paid subscriptions, billing, refunds & cancellation

When paid plans are offered, subscriptions are billed in advance on a recurring basis (typically monthly) through our payment processor and merchant of record, Lemon Squeezy. Prices and plan limits are shown on our Pricing page at the time you subscribe.

Renewal. Unless you cancel before the end of the current billing period, your subscription renews automatically for the same term at the then-current price (subject to any notice we provide under section 13).

Cancellation. You may cancel a paid subscription at any time through the billing portal linked from your account or by emailing support@compareversions.com. Cancelling a subscription stops future renewals; access and monitoring continue until the end of the paid period already billed.

Changing URL quantity. Paid plans may let you change how many URLs you can monitor through the Billing page in your account:

  • Add URLs. Extra URLs become available for monitoring immediately. There is typically no additional charge at the moment you add. Your next renewal invoice reflects the higher quantity and may include any catch-up amount calculated by Lemon Squeezy for the remainder of the current billing period. After you add URLs during a billing period, you may not be able to reduce your URL quantity until the next renewal; you may still add further URLs before then.
  • Reduce URLs. When Reduce is available, lowering quantity does not refund the current period. Your lower total takes effect at the next renewal while your current allowance remains until then.

Failed payments. If a renewal or other charge does not go through, Lemon Squeezy may mark your subscription past due and retry payment. Monitoring may continue for a limited time during that process, but adding URLs may be blocked until payment succeeds. Use Complete payment / update card or Manage billing on Billing, or contact support@compareversions.com with your account email if you need help.

After the paid period ends. When the paid period ends (including after cancellation takes effect at period end, or when a subscription expires), unless you resubscribe:

  • Scheduled monitoring and fetching for your URLs will be paused (your URLs may remain visible in the account, but they are not checked on the regular schedule);
  • We will retain your monitoring data (including URLs, snapshots, versions, diffs, and related configuration) for approximately thirty (30) days after the paid period ends so you can export or save what you need, or resubscribe;
  • If you resubscribe before that retention period ends, monitoring for your existing URLs may resume according to the quantity and plan you purchase;
  • If you do not resubscribe before the retention period ends, we will permanently delete that monitoring data. Your login account may remain (subject to Freemium and other rules in section 5a) unless you delete the account;
  • We may email you about the pause, the retention deadline, and how to resubscribe.

You may also end your use of the Services by deleting your account on the Account page, which cancels any active Lemon Squeezy subscription where applicable and permanently removes your account and related monitoring data as described in our Privacy Policy (without waiting for the post-cancel retention window above).

Refunds. Fees are generally non-refundable for partial billing periods or unused URL quota. We will refund charges where required by applicable law, where we charged in error, or where we agree in writing. If you believe you were billed incorrectly, contact support@compareversions.com within fourteen (14) days of the charge with your account email and transaction details.

Nothing in this section limits non-waivable consumer rights in your jurisdiction.

6. Content & intellectual property

Content obtained from Online Services remains the property of its respective owners. You may use Content only as permitted by those owners or by law. We do not claim ownership of your User Information.

You grant us a worldwide, non-exclusive license to host, store, process, and display User Information and Content solely to operate, secure, and improve the Services (including generating diffs and saved comparisons).

Third-party Content displayed through the Services is provided “as is.” We are not responsible for its accuracy, legality, or completeness.

7. No professional advice

The Services help detect changes in online content. They do not provide legal, compliance, financial, or business advice. You are solely responsible for decisions made based on snapshots, diffs, or alerts. We do not guarantee that all changes will be detected or that monitoring will be uninterrupted.

8. Account security

You must provide accurate registration information and keep credentials confidential. You are responsible for all activity under your account, including URLs added and fetches performed.

We may require you to confirm your email address before full access to the Services (for example adding URLs, reviewing changes, or subscribing). Until confirmation, access may be limited to the verification notice and related account actions.

9. Suspension & termination

We may suspend or terminate access to the Services, or stop monitoring specific URLs, if we reasonably believe you violated this Agreement, pose a security or legal risk, or if required by law. You may stop using the Services at any time.

Provisions that by nature should survive (including indemnification, disclaimers, and limitation of liability) survive termination.

10. Indemnification

You agree to indemnify, defend, and hold harmless Compare Versions, its affiliates, and their officers, employees, and contractors from any claims, damages, losses, and expenses (including reasonable legal fees) arising from:

  • Your use of the Services or Content;
  • Your monitoring or fetching of any Online Service without proper authorization;
  • Your breach of this Agreement or applicable law;
  • Any dispute between you and a third party relating to your monitoring activities.

This is the primary mechanism by which we operate as a neutral tool provider: misuse liability rests with the account holder who directed the activity.

11. Disclaimers

THE SERVICES AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant uninterrupted, error-free, or secure operation, or that snapshots or diffs will be complete, timely, or accurate. You use the Services at your own risk.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR LOSS OF PROFITS, DATA, OR GOODWILL.

OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM THIS AGREEMENT OR THE SERVICES SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) ONE HUNDRED US DOLLARS (USD $100).

13. Changes to this Agreement

We may update this Agreement from time to time. The “Last updated” date at the top reflects the current version. Material changes may require you to accept the updated terms before continued use. If you do not agree to updated terms, you must stop using the Services.

14. Governing law & international use

The Services are offered globally. Users may access and use the Services from any country, subject to this Agreement and applicable local law. You are responsible for ensuring that your use of the Services — including each URL you monitor — complies with laws that apply to you in your location and in relation to each Online Service.

This Agreement is governed by the laws of Bangladesh, where Compare Versions is established, without regard to conflict-of-law principles. Nothing in this Agreement limits rights you may have under mandatory consumer protection, data-protection, or other non-waivable laws of your country or region of residence.

Unless mandatory law in your jurisdiction requires otherwise, courts in Bangladesh shall have exclusive jurisdiction over disputes arising from this Agreement or the Services.
