Privacy Policy
Last updated: [DATE]
Who we are
DataFlow Convert (the "Service") is operated by [LEGAL ENTITY NAME], registered at [REGISTERED ADDRESS]. Contact: support@example.com.
For the purposes of the EU General Data Protection Regulation ("GDPR"), we are the data controller for the personal data described in this policy.
What we collect
- Account data. Your email address and a hashed password (Argon2).
- Billing data. If you subscribe, we store a Stripe customer identifier. Payment card details are handled exclusively by Stripe and never touch our servers.
- Conversion metadata. For each conversion we store: input format, output format, file sizes, status, and timestamp. We do not persist the contents of converted files.
- Session cookies. A single httpOnly cookie (
dfc_refresh) that authenticates your browser. It is strictly necessary for the Service to function. - Server logs. Operational logs (request ID, status code, path, timing) retained for up to 30 days for security and debugging.
File contents
Files you upload for conversion are stored only on disk on the conversion worker, only for the duration of the conversion, and are deleted immediately after the converted file is streamed back to you. We do not read, analyse, or retain the contents.
