Privacy Policy

Effective date: 13 April 2026 · Last updated: 13 April 2026

EPub Echo is an Android app for reading EPUB books. This page explains what data we collect and how we use it.

Short version. We collect only what is needed to run the app: your Google sign-in details, the books you upload, and your reading progress. We do not sell your data. We do not use ad or tracking SDKs.

1. Who we are

"EPub Echo", "we", "us", and "our" refer to the EPub Echo project, operated by Saransh Sinha as an independent developer. If you need to contact us about this policy or your data, email contact@epubecho.qzz.io.

2. Data we collect

3. Data we do not collect

4. How we use your data

We use your data to let you sign in, store your books, sync your reading progress, and support your account. We do not sell your data or use it for advertising.

5. Storage and security

Your data is stored on secure cloud infrastructure used by EPub Echo. Data is encrypted in transit between your app and our servers.

6. Read-aloud processing

Read-aloud runs on your Android device. The app does not record your voice.

7. Third-party services

We use trusted providers for Google sign-in, hosting, storage, and email routing. We do not use ad SDKs or tracking analytics in the app.

8. How long we keep data

We keep your account data while your account is active. If you want your data deleted, email us and we will remove your account data.

9. Your rights

10. Children's privacy

EPub Echo is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected data from a child under 13, email us and we will delete it.

11. International transfers

Your data may be stored or processed in countries other than the one you live in, because our cloud providers operate globally. Wherever it is stored, this policy and the security commitments above apply.

12. Changes to this policy

If we make material changes to this policy, we will update the "Last updated" date at the top. Continued use of EPub Echo after a change takes effect constitutes acceptance of the updated policy.
