Terms of Use

Wrenwhistle · Zydeno · 19 October 2026

These terms apply to Wrenwhistle: Stopwatch, Timer & Alarm ("Wrenwhistle"), published by Zydeno. Contact: [email protected]. Effective date: 19 October 2026.

Use

You may install and use Wrenwhistle for personal, educational and work purposes. This version is free, with no ads. Do not resell the extension or present modified copies as the original.

How it works

The extension runs entirely in your browser and stores its data only in your browser (storage.local); nothing is sent to Zydeno or anyone else; no analytics. See the privacy policy for details on data and permissions.

Timing limits

Wrenwhistle uses the alarm, notification and audio functions of your browser and operating system. Nothing can ring while the browser is closed, the computer is switched off, or the system blocks notifications or sound. Short timers can ring up to about 30 seconds late when the browser has put the extension to sleep. Do not rely on Wrenwhistle alone where a missed or late signal could cause harm, for example for medication critical to health, cooking that could cause a fire, or safety duties.

Your content

Timer names, alarm names and your own sound file are yours. Make sure you have the right to use any sound file you add.

No warranty

Wrenwhistle is provided "as is", without warranties of any kind, to the extent permitted by law. To the extent permitted by law, Zydeno is not liable for indirect or consequential damages arising from the use of the extension. Nothing in these terms limits rights you have under mandatory consumer law.

Third-party components

The bundled fonts Murecho and Sono are used under the SIL Open Font License 1.1; see THIRD_PARTY_NOTICES.md in the package. Icons, interface glyphs and the eight alarm sounds are original work by Zydeno.
