Privacy Policy

Zenotion (https://zenotion.zenscail.com) is a free, markdown-first note-taking platform for developers. This Privacy Policy explains what information we collect when you use Zenotion, how we use it, and the choices you have. By creating an account or using the service, you agree to the practices described here.

We collect only what we need to run the service:

• Account information. Your name, email address, and a securely hashed password when you sign up with email/password. If you sign in with Google, we receive your name, email address, and profile picture from Google — we never see your Google password.
• Content you create. Notes, note version history, folders, tags, note icons and cover images, and any images you upload into your notes.
• Sharing settings. Whether a note is public and its share link slug.
• Session data. Authentication cookies and session records (including IP address and browser user agent) used to keep you signed in securely.

We do not collect payment information — Zenotion is free and has no paid plans.

Zenotion's AI features (summarize, rewrite, fix grammar, translate, and other note actions) are bring-your-own-key:

• Your AI provider API keys (OpenAI, Gemini, Anthropic, Groq, OpenRouter) are stored locally in your browser — they are never saved in our database.
• When you run an AI action, the relevant note content is sent to your chosen AI provider to generate the result. Their processing of that content is governed by that provider's own privacy policy.
• We do not use your notes to train AI models, and we do not sell or share your content with advertisers.

• To provide the core service: storing, syncing, and autosaving your notes.
• To authenticate you and keep your account secure.
• To serve public share pages for notes you explicitly make public.
• To respond to support requests you send us.
• To debug problems and keep the service reliable.

We use only essential cookies — session cookies set by our authentication system (Better Auth) to keep you signed in, and a preference for your light/dark theme. We do not use advertising or cross-site tracking cookies.

Your data is stored in a PostgreSQL database and images are stored with our media hosting provider (ImageKit). We share data only with the service providers required to operate Zenotion:

• Database and application hosting providers.
• ImageKit, for storing and serving images you upload.
• Google, if you choose to sign in with Google.
• Your chosen AI provider, only when you run an AI action.

We never sell your personal data. Notes are private by default and scoped to your account; a note becomes visible to others only if you explicitly enable its public share link.

We keep your account data and notes for as long as your account is active. You can delete individual notes, folders, and tags at any time from the app.

To delete your entire account and all associated data, email us at suprrabhat.work@gmail.com and we will remove it within 30 days.

• Access and export the content of your notes at any time.
• Correct your account details.
• Delete your content or your entire account.
• Revoke Google access from your Google account security settings.
• Remove your AI API keys at any time — they live only in your browser.

Passwords are stored hashed, all traffic is served over HTTPS, and every note, folder, and tag query is scoped to the authenticated owner. No method of transmission or storage is 100% secure, but we follow industry-standard practices to protect your data.

Zenotion is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has created an account, contact us and we will delete it.

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of Zenotion after changes means you accept the updated policy.
