One person · direct support
One person builds Seryn and answers for it. Send bug reports, feature requests, Pro unlock problems, privacy requests, and general feedback through the matching support form below.
Contact: support@seryn.dev.
A reply usually arrives within two business days. Include your device, operating-system version, and app version when it matters so the first reply can be the useful one.
Before you send
- The changelog lists every shipped rev. of every product. A behavior change is often explained there.
- App data and configuration are local by default. Marzin can optionally store eligible items in your private iCloud database. Seryn operates no content server and cannot access your private iCloud library.
- Privacy is covered on the site privacy page, the Marzin privacy and terms page, the Floatnotes privacy and terms page, the Center Click privacy and terms page, the Eyelet privacy and terms page.
- Website terms are at /terms/. Refunds are covered at /refunds/.
BuyKeeper preview help
BuyKeeper is in development for iPhone and iPad. See BuyKeeper Support, its privacy information preview and use and purchase information preview. Contact support by email; never send recovery keys or unredacted receipts.
Eyelet quick help
For Eyelet, use the Eyelet Support & Feedback form. Eyelet adds no app or device data to the form URL.
- Eyelet appears in the menu bar and does not add a Dock icon.
- Click the menu bar eyes to open presets, Behavior, Eye Studio, Help, and Settings.
- Use Presentation pause or a timed quiet mode when you want less movement.
- Automatic reactions and menu-bar reminder popups are off by default. Some HDMI and DisplayPort devices do not expose software volume or mute values, so audio reminders may be unavailable.
Marzin Pro restoration
If Pro is missing, use Restore Purchases with the Apple Account used to acquire Pro. On iPhone and iPad, check the account under Media & Purchases; it can differ from your iCloud account. Do not buy Pro again to troubleshoot an unlock. Include the app version and whether you are using the App Store or TestFlight when contacting support; never send your password or payment details.
What support cannot do
App Store purchases, refunds, payment methods, receipts, and Apple Account issues are handled by Apple. Seryn can help debug unlock or restore state, but refund requests start at reportaproblem.apple.com.
