Can I delete my submissions from GPTZero?

Yes. Logged-in users can delete individual scans from their dashboard, and you can contact GPTZero support to request deletion of your account data. If you are using the free anonymous tool you have fewer controls, but you can avoid submitting identifying information in the first place.

Does GPTZero train its AI on submitted text?

GPTZero reserves the right to use aggregated and anonymised data to improve its models. Whether your specific submission is used depends on your account type and whether you have opted out.

Is GPTZero safe for student work?

For institutional accounts that sit under a data processing agreement, GPTZero is generally treated as safe for student work. For individual student use of the public tool, assume submissions may be stored. Avoid pasting personal information alongside essays.

How do other AI detectors compare on privacy?

Detectors vary widely. Turnitin retains submissions long-term as part of its similarity database. Copyleaks offers enterprise data controls. Originality.ai stores scans by default. Writer.com advertises no data retention. Always read the current privacy policy before submitting sensitive work.

Does GPTZero Save Your Work? Privacy and Data Retention Explained

Q: Does GPTZero save your work?

Yes. GPTZero stores submitted text on its servers by default to run its detection models and, according to its privacy policy, may retain content to improve its classifiers. Content submitted through institutional accounts is handled under those contracts; content from free and individual paid accounts can be kept unless you opt out or delete it.

You ran your essay through GPTZero before submitting it to Turnitin. Good instinct. But now a different question: does GPTZero still have a copy of that draft on its servers?

Short answer: yes, by default. GPTZero stores the text you submit to run detection and, per its privacy policy, may retain it to improve its classifiers. Institutional accounts follow separate contracts; free and individual paid users can delete history from the dashboard or by contacting support.

If you only need to strip invisible Unicode watermarks without sending prose to a detector's training pipeline, try the Human Writes watermark checker first.

What GPTZero actually stores

When you paste text into GPTZero, a few things happen:

The text is sent to GPTZero's servers so the classifier can score it.
The scan result (and, for logged-in users, the submitted text) is saved in your account history.
GPTZero's privacy policy reserves the right to use submissions, in aggregated or anonymised form, to improve its detection models.

That means "does GPTZero save your work?" has two answers:

Short term: yes. The text must be transmitted to their servers to be analysed.
Long term: yes by default, unless you are on an institutional contract that restricts retention, or you explicitly delete the submission.

This is standard for hosted AI detectors. What varies between providers is how long the data is kept, whether it is used for training, and how easily you can delete it.

How to reduce what GPTZero keeps

If you want to use GPTZero but minimise what it stores:

Use the dashboard's delete option. Logged-in users can remove individual scans from the history panel.
Request account deletion. GPTZero's support team will remove your account and associated submissions on request.
Avoid pasting personal data. Strip names, email addresses and identifying details from text before submitting.
Use your institution's account. University-managed contracts usually impose stricter retention and training limits than the public free tier.
Check for watermarks locally first. Running text through our watermark checker removes invisible Unicode watermarks without sending the content to a third-party detector.

How GPTZero compares to other detectors on privacy

Privacy practices vary meaningfully across the major detectors. The table below summarises how each one handles submitted text (as of the most recent policies available; always verify directly before submitting sensitive work).

Detector	Stores submitted text?	Uses it for training?	User-controlled deletion?
GPTZero	Yes, by default	Aggregated / anonymised	Yes, from dashboard or support
Turnitin	Yes, long-term as part of similarity database	No (contractually)	Institution-controlled
Copyleaks	Yes, with enterprise retention controls	Enterprise opt-out available	Yes
Originality.ai	Yes, scans saved to account	Aggregated / anonymised	Yes, from dashboard
Writer.com	Advertises no retention	No	N/A (no account needed)

What this means for students

If you are a student self-checking an essay before submission, the practical implications are:

Your text is leaving your device. Do not paste anything you would not share with the detector's developers.
Institutional GPTZero accounts are safer than the public tool. If your school offers one, use it.
False positives are not erased by deletion. Even if you remove a scan from your history, any flag generated during class grading lives in your instructor's copy, not yours.
Privacy matters alongside accuracy. A detector that saves your work forever and then misidentifies it as AI-written is the worst of both worlds. See our guide to false positives in AI detection.

What this means for educators

For teachers and administrators, the privacy question is really a procurement question:

Choose the institutional tier. The public GPTZero tool is not bound by the same DPAs as institutional contracts.
Document retention in writing. Ask for retention windows and training-exclusion terms to be spelled out in the contract.
Build student consent into policy. If you require students to run their own work through a detector, tell them what the detector does with their submissions.
Avoid detector-only verdicts. Regardless of privacy practices, no detector is accurate enough to base a grade decision on by itself.
