Privacy Policy

Effective date: 27 October 2026 · Last updated: 28 October 2026

The short version

• There is no essay archive. It's sent to a third-party detection service, scored, and returned to your browser.
• There is no account. We don't ask for a name, email or password to check an essay.
• A functional cookie enforces the daily free-check limit.
• Our analytics use no cookies. Umami measures page visits and tool interactions. We do not use advertising analytics or sell data.
• We only learn your email if you write to us.

1. Who we are

AI Essay Checker ("we", "us") operates aiessaychecker.io. For anything in this policy: privacy@aiessaychecker.io.

2. What we process, and why

Essay text you submit. Sent over HTTPS to a third-party AI detection service; the scored result is returned to your browser. We do not persist the text, and we do not use it to train models. We request no-retention handling where the service offers it; otherwise the service’s own retention terms apply to what it receives, including usage metadata. We cannot retrieve an essay after your session ends because we have no essay archive.

An anonymous identifier cookie. Named __Host-aec_identity, set by us, HttpOnly, Secure and SameSite=Lax, valid up to 30 days. It contains a signed random ID, not your essay or contact details. Purpose: count how many checks have been used today so the free limit can be enforced. It is not used for advertising or profiling. Clearing cookies replaces this identifier but does not reset all rate limits.

Technical request data. Our Cloudflare hosting processes IP addresses and browser headers to deliver and protect the site. IP and request logs are kept for up to 30 days, then discarded. We do not put essay text in application logs.

Abuse prevention. When you submit a check, FingerprintJS creates an identifier from browser and device characteristics, including rendering capabilities. Its usage reporting is disabled. Cloudflare Turnstile also runs a challenge in your browser; it is usually invisible but may occasionally ask you to confirm you are human. Our server verifies the resulting single-use token with Cloudflare, together with your IP address. Cloudflare rate limiting and our Cloudflare Durable Objects quota store enforce limits using your browser identity, fingerprint, IP address and approximate country. The quota store keeps daily keyed hashes and usage counts, not essay text or raw fingerprint components. Live quota records are cleared after the UTC day ends. Similar browser fingerprints or shared networks can share limits, and failed checks may count toward the quota.

Temporary browser storage. A Re-check transfer may temporarily place text in this tab's session storage. It is consumed on arrival at the checker and expires for use after five minutes; closing the tab clears it. Copying text places it on your clipboard only when you select Copy text. Your theme choice is kept in local storage as site-theme until you change it or clear browser storage.

Aggregate usage analytics. Umami measures page visits and tool interactions, including word counts, detection scores and button clicks, without cookies. It also processes browser and device information and approximate location. Our site-sent analytics events do not include essay text, browser fingerprints, abuse-prevention identities or URL query parameters. We do not assign analytics user IDs or enable session recordings.

Emails you send us. Kept as long as needed to answer, then deleted unless there's a legal reason to keep them.

Outbound clicks. When you click a link to a partner site, you leave our site; the partner may set its own cookies under its own policy. The affiliate URL includes our referral code. We do not send your essay to the partner; it receives normal browser request data when you follow the link.

3. What we never do

Sell or rent personal data · use your essay to train models · build advertising profiles · require an account to use the checker · share your text with anyone beyond the detection provider named above.

4. Third parties

Each service has its own terms and privacy policy. Umami is cookieless.

5. Retention at a glance

6. Your rights

Depending on where you live (GDPR, UK GDPR, CCPA/CPRA and similar), you may have the right to access, correct, delete, restrict or object to processing, and to complain to a supervisory authority. Write to privacy@aiessaychecker.io and we'll respond within 30 days.

An honest caveat: we hold no account records and no essay archive. Cookies, request logs, analytics identifiers or support emails may still relate to you, and we may need more information to locate a relevant record. Where we can act — deleting a support email, clearing a rate-limit record — we will.

7. Children

The service is intended for users 13 and older. If you're under 18, use it with the knowledge of a parent, guardian or teacher. We do not knowingly collect personal information from children under 13; if you believe a child has sent us personal data, contact us and we'll delete it.

8. International transfers

Our providers may process data outside your country. Locations and transfer safeguards depend on the provider and service configuration; their terms and privacy policies describe these arrangements.

9. Security

HTTPS everywhere; server-side essay text held only in memory for the length of a request; temporary browser storage handled as described above; rate-limit and log stores restricted to the minimum needed. No system is perfectly secure, but the best protection here is architectural: we don't collect what we don't need.

10. Changes

Material changes will be posted on this page with a new effective date. If a change ever expands what we collect, it will be stated in plain language at the top, not buried in a revision history.
