Privacy policy
Last updated: 25 October 2026
Short version: SyncProof works on your own computer. Your videos are never uploaded to us or anyone else. This website doesn't track you.
The SyncProof app
- Your videos stay on your PC. Checking and fixing run entirely on your computer's CPU. SyncProof doesn't upload your video, audio, frames, faces or reports anywhere.
- Reports stay local. The reports SyncProof creates are saved on your computer, where you choose. They only go somewhere if you send them yourself.
- No analytics or telemetry. The app doesn't send usage statistics or crash reports, and it doesn't check for updates.
- Licence check. The free version never goes online. When you activate Pro, the app checks your licence key with Gumroad, then again every few days while you're online (it keeps working offline for up to 14 days). It sends only the product ID, your licence key and the app's name and version, never anything about your videos or your computer.
This website
- No cookies, no analytics, no advertising or tracking scripts, and no fonts or scripts loaded from other sites.
- The site and downloads are served by Cloudflare. Like any web host, Cloudflare processes your IP address and the page you request to deliver and protect the site. We only see totals (visits, downloads per month), never who visited.
- Activation reset form. If you use it, we send your licence key to Gumroad to check it against your purchase email and lower its activation count. To stop abuse we keep a scrambled (hashed) copy of the key for 30 days and a scrambled copy of your IP address for one hour. Nothing else is stored.
Buying SyncProof
Purchases are handled by Gumroad. They process your payment and send your receipt and licence key, and their own privacy policies apply. We receive your name, email address and order details so we can provide your licence, support and refunds. We don't receive your full card details.
Support emails
If you email us, we use your message and email address only to help you. You may get one automatic reply a day pointing to the matching help page. For our weekly support summary we keep only the subject line and topic of each email, for five weeks. If you choose to send a sample file or a report so we can look at a problem, we use it only for that and delete it when the issue is closed.
Your choices
You can ask us what personal data we hold about you (normally just your purchase record and any emails), and ask us to correct or delete it, unless we have to keep it for tax or accounting reasons.
