Privacy policy

Last updated: October 8, 2026

In one line: BearWiki is local-first. Your notes live as Markdown files on your own devices. Content is uploaded to the cloud only when you choose to sign in and turn on sync.

We have no advertising, tracking, behavior analytics or crash-reporting SDKs. We do not sell, rent or trade any of your data.

1. What we collect

Without signing in: nothing is collected

If you never create an account, BearWiki is a purely local app. Your documents, images and settings are all kept on your device, and no data ever leaves it. We therefore have no way of knowing who you are or what you write.

After signing in and turning on sync

DataWhy it is needed
Email addressIdentifies your account, for signing in and account recovery
PasswordStored only as a salted hash; we cannot see your original password
Document content and file pathsRequired for cross-device sync
Document version historyUsed to keep both versions on a sync conflict, so no data is lost
Images in documentsRequired for cross-device sync
Device identifierRandomly generated, used to tell sync sources apart; contains no hardware identifiers

2. What we explicitly do not do

3. Where your data is stored

About encryption, honestly: data is encrypted in transit with HTTPS. But the server stores it in plaintext, and we do not currently offer end-to-end encryption. This means that, technically, we are able to read your cloud content (we will not; access is restricted by row-level security policies, so each account can only read its own data). If your notes contain highly sensitive information, please decide for yourself whether to turn on sync. We believe stating this clearly is more responsible than vaguely claiming “bank-grade encryption”.

4. What AI features send out

When you use AI features such as Ask, BearWiki sends the note content relevant to your question, together with your question, to the LLM provider that you configured yourself.

5. Your rights

6. How to delete your data

Deleting a single document

Delete it in the app; the corresponding cloud content is marked as deleted as well.

Deleting your account (removes all cloud data)

In the app, go to Settings → Account → Delete account and enter your email when prompted to confirm. We will then permanently delete:

This action is irreversible, and it does not delete the local documents on your device. They are yours, and it is up to you whether to keep them.

7. Data retention

Cloud data is kept for as long as your account exists, to support cross-device sync. It is deleted immediately when you delete your account, with no retention period and no backup archive.

8. Share links

If you create a share link, the document it points to will be accessible to anyone who has the link, including people who are not signed in. You can revoke a share link in the app at any time, and it stops working immediately.

9. Children

BearWiki is intended for adult knowledge workers. It is not designed for children under 14, and we do not knowingly collect their personal information. If you believe a minor has provided personal information to us, please contact us and we will delete it promptly.

10. Changes to this policy

If this policy changes, we will update the “Last updated” date at the top of this page. For significant changes (for example, a new type of data collection), we will show a prominent notice in the app.
