Privacy Policy

ConvertFlow · Last updated November 12, 2026

This policy explains what information ConvertFlow collects when you buy and use ConvertFlow Desktop (“the app”), and what we do with it. Questions? Email support@convertflow.cc.

Your files stay on your computer

ConvertFlow converts, compresses and enhances media locally on your computer. Your video, audio and image files are never uploaded to us, and we cannot see them.

The free online converter

Files you drop into the free converter on this website are processed entirely inside your browser and are never uploaded to us. To count your free conversions we save a small counter in your browser’s local storage. We do not use advertising trackers on this website.

What we collect

• Purchase details. When you buy, Stripe collects your payment information and email address. We receive your email address, a payment confirmation and Stripe’s customer and order identifiers. We never see or store your full card number.
• License and activation data. We store a protected (hashed) form of your license key, its status (for example active or refunded), and a random installation ID for each computer you activate, with the time of activation. The installation ID is generated by the app and is not linked to your name or hardware details.
• Settings. Your preferences (theme, output folder, quality) are saved only on your computer.
• Support messages. If you email us, we keep your message and address so we can help you.

The app does not include advertising or analytics trackers.

How we use it

• To deliver your license key (on the confirmation page and by email) and let you activate the app.
• To check that a license is still valid, including switching it off after a refund.
• To limit each license to 3 installations and prevent misuse.
• To answer support requests, handle refunds, and meet tax and legal obligations.

We do not sell your personal information.

Services we use

• Stripe processes payments (stripe.com/privacy).
• Supabase hosts our license database and activation service (supabase.com/privacy).
• Resend sends your license key email to the address you used at checkout (resend.com/legal/privacy-policy).
• Cloudflare hosts this website and may log standard technical request data such as IP address (cloudflare.com/privacypolicy).

How long we keep data

We keep license and purchase records for as long as your license exists and as required for accounting, tax and fraud prevention. Support emails are kept only as long as needed to help you.

Your choices

You can ask us to access, correct or delete the personal information we hold about you by emailing support@convertflow.cc. Deleting your purchase record will deactivate your license. Some records may need to be kept where the law requires it.

Children

ConvertFlow is not directed to children under 13, and we do not knowingly collect their information.

Changes

We may update this policy. The date at the top shows when it last changed. Continued use of the app after an update means you accept the new version.
