Dark Calendar ("the App") is a Windows desktop calendar application developed and distributed by Hyojin Kim ("the Developer"). This policy explains how the App handles your information.
1. Summary
The Developer does not collect any personal data. The App has no server, no account system, no analytics, and no advertising.
All schedules, tasks, and settings you create are stored only on your PC.
Data leaves your device only through features you explicitly enable (Google Calendar sync, weather widget, ICS subscriptions), and only to those service providers.
2. Data stored locally
The App stores the following on your PC under %LOCALAPPDATA%\kimhyojin\Dark Calendar:
Auth tokens are stored only on your PC, encrypted with Windows DPAPI, and never sent to the Developer.
When you disconnect, the App requests token revocation from Google and deletes the local token.
The App's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
3.2 Weather widget
The city name you type is searched locally in the GeoNames city dataset bundled with the App and is not sent externally.
The resulting latitude and longitude (rounded to four decimal places), together with standard web request information such as your IP address, may be sent to MET Norway (api.met.no) to retrieve weather data. MET Norway stores API access logs in its own data center in Oslo, Norway.
Weather data is provided under MET Norway's CC BY 4.0/NLOD 2.0 terms, and city data is provided by GeoNames under CC BY 4.0.
Device location (GPS, etc.) is never collected or used.
3.3 ICS calendar subscriptions
The App fetches events from ICS URLs you enter yourself. Standard web request information (such as your IP address) may be visible to the operator of that URL.
4. Retention and deletion
All data remains on your PC until you delete it.
Disconnecting Google sync: revokes and deletes the token. You can also revoke access anytime at Google Account permissions.
Full deletion: uninstall the App, then delete the %LOCALAPPDATA%\kimhyojin\Dark Calendar folder to remove all data.
5. Children's privacy
The App collects no personal data and therefore collects no data from children.
6. Changes to this policy
If this policy changes, the updated version and effective date will be posted on this page.
