Privacy Policy

Last updated: 7 October 2026

This policy describes what the ExamDNA Android app and this website actually do with your data. We have written it to be specific rather than reassuring.

Who we are

ExamDNA is an exam-preparation app for Android, currently in closed beta. You can reach us at contact@examdna.tech.

What stays on your device

Original source files — notes, slides, PDFs, photos and similar course materials — are stored locally. Text recognition runs on the device. Your answer history, confidence ratings, study progress and Exam Replay logs are kept in on-device storage. PDF, PNG and DOCX exports are rendered on the device.

What is sent for analysis

When you generate an exam, verify questions, build an Exam DNA or run related AI features, compact evidence excerpts from your material are sent through ExamDNA's cloud functions (Cloud Functions for Firebase) to an AI model provider — currently Google Cloud Vertex AI. Excerpt size is capped. These excerpts are your course content; we don't describe them as "anonymized".

Handwritten answers are transcribed on the device first; a cloud transcription path is used only when on-device confidence is too low.

Accounts and service data

Sign-in uses Firebase Authentication. Firestore stores your account, usage counters and subscription status. Firebase App Check may be used to verify that requests come from the genuine app. RevenueCat manages subscription entitlements when billing is enabled.

Usage logs

Server-side AI usage logs record the operation type, model, token counts, cost units and success or failure. They do not contain a copy of your notes. The app does not include Firebase Analytics or Crashlytics.

Waitlist

If you join the waitlist on this website, we store your email address only to send you a beta invite and launch news. Your submission is delivered to our inbox via FormSubmit. Ask us any time at contact@examdna.tech and we'll remove it.

What we don't claim

  • We don't claim that everything stays on your device — AI features need excerpts to be analyzed in the cloud.
  • We don't claim zero telemetry — usage and account records exist as described above.
  • We don't sell your files or your data.

Your choices

You can delete courses and sources in the app at any time, which removes them from your device. To request deletion of your account or waitlist data, email contact@examdna.tech.
