Terms of Service

Last updated 2026-11-09

These Terms of Service ("Terms") govern your use of CheckMate.bio (the "Service"), operated by IASolutions. By using the Service you agree to these Terms. If you do not agree, do not use the Service.

1. Description of the Service

CheckMate.bio is a reverse email lookup and OSINT service. You submit an email address and we return a report of accounts and profile metadata associated with that address on online services and in data-breach indexes.

  • The free search shows which kinds of sites an email address is found on, with most details hidden. It is limited to 3 searches per 7 days per IP address.
  • A detailed report costs $0.99 USD, paid once.
  • A bundle costs $2.99 USD for 5 detailed reports or $4.99 USD for 10, for any email addresses, to use within 90 days.
  • Prices are in US dollars. You can pay with PayPal, with a debit or credit card through PayPal (no PayPal account needed), and with Venmo, Apple Pay or Google Pay where they are available.

2. Eligibility and geographic restrictions

The Service is not offered to residents of the European Union, the European Economic Area, or the United Kingdom. You represent that you are accessing the Service from outside these regions and that you are at least 18 years old and legally able to enter into a binding contract.

3. Acceptable use: legitimate interest only

You agree to use the Service only where you have a genuine legitimate interest. Examples include:

  • Personal safety checks on people you are about to meet or transact with.
  • Due diligence on potential business partners or collaborators.
  • Auditing your own digital footprint.
  • Investigating suspicious activity linked to an email you control or administer.

4. Prohibited use

You must not use the Service to:

  • Stalk, harass, threaten, or intimidate any person.
  • Investigate, profile, or compile information about minors.
  • Make or support decisions about a person's eligibility for employment (including work as a contractor, volunteer, nanny or caregiver), housing, credit, insurance, a professional license or a government benefit, or for any other purpose covered by the US Fair Credit Reporting Act (FCRA) or similar state laws.
  • Bulk-enumerate email addresses, resell the Service, or scrape results to construct a derivative database.
  • Violate any law, regulation, or third-party right, or induce us to do so.
  • Attempt to bypass the free-search limit, rate limits, payment verification, or any other security control.

CheckMate.bio is not a consumer reporting agency as defined in the FCRA, and its reports are not consumer reports. If you need information for one of the decisions above, use a consumer reporting agency that complies with the FCRA.

We may suspend or terminate access for any user we reasonably believe is violating these rules, without notice and without refund.

5. Payment and refunds

The detailed report ($0.99 USD) and the bundles ($2.99 and $4.99 USD) are one-time digital products. By purchasing, you acknowledge that the search starts immediately after payment, that a report is usually ready within a few minutes, and you waive any right to cancellation that would otherwise apply to digital content.

5.1 No-high-confidence-data refund

If your $0.99 detailed report contains no matches with a confidence score of 50% or higher (that is, every match falls into the "Possible matches" low-confidence section), you may request a full refund by emailing support@checkmate.bio within 14 days of the purchase. Include the PayPal transaction ID from your PayPal receipt and the report's PDF or a screenshot of it: we delete reports after 24 hours, so we check the request against what you send. If the condition is met, we refund the $0.99 fee to the original payment method.

5.2 Bundles

A bundle is refundable only if a technical error on our side kept you from using it. A bundle search that fails on our side returns its credit to the bundle automatically. Unused searches expire with the bundle after 90 days.

5.3 Other refunds

We may, at our sole discretion, refund a purchase where the Service failed to produce any report due to a technical error on our side. No refund is offered for dissatisfaction with the content of a report that correctly reflects its sources.

If a payment is refunded, reversed, or disputed, we cancel what it bought: the report, or the bundle and its remaining searches.

6. Data ownership and use of reports

Reports are provided to you for your own informational use only. We keep a paid report for 24 hours and free results for 10 minutes, then delete them; export the report as a PDF if you want to keep a copy. You are responsible for how you use, store, and share any report you retrieve, and for complying with applicable law when you do so.

7. No warranty: Service "AS IS"

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. WE DISCLAIM ALL WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, AND UNINTERRUPTED AVAILABILITY.

Results are generated from third-party sources, including data-breach indexes, and may be incomplete, outdated, or incorrect, and a match found through a username may belong to a different person. You must not rely on the Service as the sole basis for any consequential decision. Treat every report as a lead, not a conclusion.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IASOLUTIONS AND ITS AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF, OR INABILITY TO USE, THE SERVICE.

OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR $5.00 USD, WHICHEVER IS GREATER.

9. Indemnification

You agree to defend, indemnify, and hold harmless IASolutions from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising from your use of the Service or your violation of these Terms, including any prohibited use listed in Section 4.

10. Changes to the Service and these Terms

We may modify, suspend, or discontinue any part of the Service at any time. We may also revise these Terms. Material changes will be reflected by updating the "last updated" date at the top of this page. Your continued use of the Service after changes take effect constitutes acceptance.

11. Governing law and disputes

These Terms are governed by the laws of the jurisdiction where the operator (IASolutions) is established, excluding its conflict-of-law rules. Any dispute arising out of or relating to the Service or these Terms shall be resolved in the competent courts of that jurisdiction, unless applicable consumer-protection law grants you a non-waivable forum.
