Data we collect

Postvolve may collect and store the following data:

  • User email address
  • User subscription plan
  • Daily usage count
  • Authentication session data required to keep the user logged in

This data is stored using Supabase.

Authentication

Postvolve uses Google login through Supabase authentication.

When a user signs in, Postvolve may store Supabase access tokens and refresh tokens in chrome.storage.local to keep the user authenticated inside the Chrome extension.

Text processed by Postvolve

Postvolve only reads the text written by the user inside the X composer when the user actively clicks one of Postvolve’s action buttons, such as Improve, Translate & Adapt, or refinement buttons.

Postvolve sends the selected composer text and optional user instructions to the Postvolve backend in order to generate improved versions, translations, adaptations, or variants.

AI processing

When AI mode is active, the text and instructions provided by the user may be processed by OpenAI to generate the requested output.

Postvolve does not use AI processing unless the user actively requests an action through the extension interface.

Payments

Paid plans are managed through Stripe.

Stripe may process payment information according to its own privacy and security policies. Postvolve does not store full credit card details.

Feedback

User feedback may be collected through Google Forms and stored in Google Sheets.

Feedback submission is optional.
