Privacy
SyncMarkr records markers, not footage. This page describes the app as it is being built; it will be updated before release if anything here changes.
Last updated 27 September 2026.
Your video never leaves your device
SyncMarkr does not upload, copy, or transmit video. Footage stays on your camera card and on the device you imported it to. There is no video storage on our servers, and no feature that would put it there.
Clips you save to Photos are written to your photo library on this device and nowhere else. SyncMarkr asks for permission to add to your library the first time you save a clip; it never asks to read it.
When the app records that a camera file exists, it stores only what it needs to line markers up against it: the file name, its start timecode, how long it runs, and its frame rate.
Why the app uses your camera
SyncMarkr reads timecode from your camera’s monitor. You aim the device at the display and the app recognises the digits so it can start its own clock at the same instant.
Those frames are processed on your device, in the moment, only to read the digits. They are not recorded, not saved, and not transmitted anywhere. The app does not use the camera at any other time.
What is stored in your account
If you sign in, the following syncs so your work reaches your other devices:
- Your email address, or the identifier Sign in with Apple provides
- Project names
- Sessions: when they ran, the frame rate, and the timecode the app locked to
- Markers: their timecode, label, and any note you add
- Your marker buttons — labels, colours, and timing offsets
- Camera profiles: their names, frame rates, and measured display lag
- The camera-file details described above
The app works without an account. If you never sign in, none of this leaves your device.
What is never collected
- Video or audio recordings of any kind
- Your location
- Contacts, photos outside what you explicitly import, or device identifiers for tracking
- Analytics or usage tracking — the app contains no analytics SDK
- Advertising identifiers. Nothing here is sold or shared with advertisers
Where it is stored
Account data is held on Supabase, on servers in the United States. Access is restricted to your own account by database-level policies, so one account cannot read another’s data.
Who it is shared with
Nobody. Data is not sold, rented, or handed to third parties for their own use. The only companies who touch it are the ones running the infrastructure it sits on, acting on our instructions.
Deleting your data
To delete your account and everything stored for it, open Settings in the app and choose Delete account. Your cloud data is removed straight away. Deleting your account does not touch anything on your device or your cards.
For a copy of your account data, or if you can’t reach the app, email support@syncmarkr.com from your account’s address.
Children
SyncMarkr is a tool for camera operators and is not directed at children. We do not knowingly collect data from anyone under 13.
Changes
If this policy changes in a way that affects what is collected, the date above changes with it and the app will say so.
