Information We Collect

When you sign in with Google OAuth, we collect the following information from your Google account:

  • Email address — Used as your unique identifier and for account recovery.
  • Display name — Used to personalize your profile.
  • Profile picture URL — Displayed as your avatar.

We do not request access to your Google Drive, contacts, calendar, or any other Google services.

Data Storage & Security

Your account data is stored in a distributed rqlite database cluster with the following security measures:

  • Data is encrypted at rest and in transit (TLS 1.3).
  • Database nodes are deployed in isolated networks with restricted access.
  • Passwords (for email-based accounts) are hashed using bcrypt with a cost factor of 12.
  • We perform regular automated backups with 30-day retention.

Cookies & Sessions

We use a minimal set of cookies for essential functionality:

  • auth_token — A JWT containing your user ID, email, and nickname. Expires after 30 days.
  • lang — Stores your preferred language. Contains no personal data.

We use analytics technologies and, only after your advertising consent, Google AdSense / Infolinks cookies or similar storage to deliver and measure ads. You can reject advertising cookies without losing access to the tools.

Local File Processing

All file processing happens locally in your browser using WebAssembly (WASM).

  • PDF, image, video, and file conversion tools use WASM to process files on your device.
  • Your files are never uploaded to our servers for processing.
  • We have zero access to the content of any file you process.
  • AI image processing models run on your device's GPU via ONNX Runtime Web.

Third-Party Services

  • Google OAuth — For authentication.
  • Stripe — For payment processing. We do not store your credit card information.
  • Google AdSense — For displaying and measuring ads after advertising consent. Google may process device, usage, and approximate location data under its own privacy terms.

  • Access — Request a copy of all personal data we hold about you.
  • Correction — Update your profile information at any time from your account page.
