Privacy Policy

Slate Gannet · Zydeno · 19 October 2026

Slate Gannet: Screen Recorder ("Slate Gannet", "the extension") is published by Zydeno. Contact: [email protected]. Effective date: 19 October 2026.

In short

The extension stores data only in your browser (storage.local and the extension’s own IndexedDB); nothing is sent to Zydeno or anyone else; no analytics.

Slate Gannet has no account, no server, no upload, no telemetry, no advertising and no remote code. It makes no network requests. It does not read, change or watch the websites you visit.

What is recorded, and only when you start it

A recording starts only after you press Start recording and choose a tab, window or screen in your browser’s own sharing dialog. While it runs, the browser shows its own sharing sign. The extension cannot see your screen, microphone or camera without that step.

The microphone and the camera are used only when you switch them on; the browser asks you for permission first. Tab or system sound is recorded only where the browser offers it and you tick it in the dialog.

What is stored in your browser

Takes (the recorded video, written in one-second pieces so an unfinished take can be recovered), their name, date, length, size, picture size and your trim points. The last 5 takes are kept; older ones are removed automatically.

Settings: source choice, microphone and camera choice and device, tab sound, camera bubble size and position, countdown, quality, frame rate, file type, pointer, theme and language. What a real share showed (for example that tab sound arrived) is remembered to describe this browser correctly.

All of this stays in the extension storage of this browser profile. You can delete one take (with Undo) or all takes at any time. Removing the extension deletes them too.

Permissions and why they are needed

storage: keeps your settings in storage.local.

unlimitedStorage: lets long takes be stored in the extension’s IndexedDB while you record, so that a take is not cut off by the default storage limit and can be recovered after a crash.

The extension asks for no access to websites, tabs, browsing history, downloads or the clipboard. Screen, microphone and camera access is granted by you in the browser’s own prompts for each use, not by the extension manifest.

Files you save

Save writes a video file (WebM, or MP4 where your browser can write it) to your downloads. Settings export writes a small JSON file with your settings. You decide where these files go and who gets them. Settings import reads a file you choose and checks it before anything is changed.

Children

The extension collects no personal data from anyone, including children.

Links

Links to zydeno.com, the support e-mail address or the store page open only when you click them; the privacy policy of that site then applies. This policy covers the extension only.

Changes

If this policy changes, the new version is published at the same address with a new effective date. Questions: [email protected].
