Privacy Policy
Last updated: 10 June 2026
This policy describes how Check If Email Is Valid ("we", "us") handles personal data on checkifemailisvalid.com, in line with the EU and UK General Data Protection Regulation (GDPR).
1. Addresses you check
An email address you submit for checking may be the personal data of a third party. We process it transiently, solely to perform the verification: the address is validated, compared against DNS records and queried against its mail server, and a result is returned to you. We do not send mail to checked addresses, do not build lists from them, and do not share or sell them. Results saved to an account remain there only so you can review and download them; short-lived operational logs used for debugging and abuse prevention are purged automatically on a rolling basis. For addresses you submit, you are the controller and we act as processor.
2. Quota tracking by IP
Free checks on this page are limited per day. To enforce the limit we store your IP address with a daily counter — a legitimate interest in protecting a free service from abuse (Art. 6(1)(f) GDPR). These records expire automatically after a short rolling window and are used for nothing else.
3. Accounts
If you create an account we process your email address, password hash, credit balance and usage history to provide the Service (Art. 6(1)(b) GDPR). Account emails are transactional only.
4. Payments
Credit purchases are processed by Stripe. Your card details go directly to Stripe and never reach our servers; we receive only a payment reference, amount and the last four card digits. Stripe acts as an independent controller for payment data.
5. Cookies
Only strictly necessary cookies are used (e.g. dashboard sessions). No advertising or third-party analytics trackers run on this site.
6. Retention
Saved results: until you delete them or your account. IP quota records and operational logs: days, not months. Billing records: as long as tax law requires.
7. Transfers
Any processing outside the EEA/UK is protected by adequacy decisions or standard contractual clauses with our infrastructure and payment providers.
8. Your rights
You may request access, rectification, erasure, restriction or portability of your data, object to legitimate-interest processing, and complain to a supervisory authority. If your address was checked by one of our users and you have questions, contact us and we will respond within the statutory timeframe.
