StackLatte is a local-first application. Your project data is stored exclusively in your browser's local storage. Nothing is transmitted to any server. We do not use cookies, analytics, or tracking of any kind.
| Storage key | Purpose | Type | Expires |
|---|---|---|---|
| eos_projects | Your project, track, and step data | Strictly necessary | Until you clear browser data |
| eos_privacy_acknowledged | Records that you have seen this notice | Strictly necessary | Until you clear browser data |
Both entries are browser local storage (not HTTP cookies). They never leave your device.
StackLatte uses the Geist typeface via Next.js' built-in font optimization. Fonts are downloaded and self-hosted at build time no requests are made to Google Fonts or any other external font service when you visit the site.
Under the General Data Protection Regulation (GDPR) you have the right to access, rectify, and erase any personal data we hold. Because all data is stored locally in your own browser, you can exercise these rights directly:
Since we hold no data on our servers, there is no central record to request deletion from. All data resides solely on your device.
The browser local storage entries described above are strictly necessary for the application to function. Under Article 5(3) of the ePrivacy Directive and Recital 47 of the GDPR, strictly necessary storage does not require prior consent. We still display an information notice on first visit in the interest of transparency.
If we add features that involve data collection (e.g. analytics or cloud sync), this policy will be updated before those features go live and you will be asked for explicit consent at that time.
Questions about this policy can be sent to privacy@stacklatte.com.
