Privacy & storage

Clear choices, no hidden tracking

Blink 2 is local-first. Optional analytics and local recent-file history stay off until you allow them, and you can change your choice at any time.

PDF and image tools

PDF, JPG, and PNG processing runs in your browser. Those files are not uploaded for normal PDF and image editing.

Office and HTML conversion

Word, spreadsheet, and HTML files up to 4 MB are sent to Blink 2's conversion endpoint. A request-specific temporary workspace is removed after the response.

Accounts and payments

Supabase handles account email, authentication, and subscription status. Stripe handles checkout and billing; Blink 2 does not store full card details.

Analytics

Vercel Analytics and Speed Insights load only after you opt in. They measure page use and performance, not advertising profiles.

What your browser remembers

“Cookies” is often used as a catch-all. Blink 2 mainly uses browser storage such as localStorage and IndexedDB; your controls cover both.

Login & security

Keeps you signed in securely through Supabase.

Necessary when you use an account

Your controls

Turning off recent PDFs deletes Blink 2's local PDF history on this device. You can also clear the current account's history directly from the account page. Withdrawing analytics consent stops analytics after the page reloads.
