Privacy Policy

Effective July 10, 2026 · Wallpaper Calendar, a DCG app

The short version: Wallpaper Calendar is a local-first desktop app. Your events live in files on your own computer. We run no servers that receive, store, or process your calendar data, we require no account, and we collect no analytics or telemetry.

Data stored on your device

Events, tasks, notes, settings, and your Pro license key are stored in plain files under your own Windows user folder (%LOCALAPPDATA%\WallpaperCalendar). They stay on your machine, are kept when you update or uninstall, and can be deleted by you at any time by removing that folder.

Google user data (optional Google Calendar sync)

If — and only if — you connect a Google account, the app syncs events two-way between your device and Google Calendar using the calendar.events permission. Specifically:

Google Calendar data is accessed solely to display and synchronize your events between the app on your device and your Google Calendar.
All processing happens on your device. Your calendar data is transmitted only between your computer and Google's own API — never to us or any other party.
Sign-in tokens are stored locally on your device and can be revoked at any time via the Disconnect button in the app or at myaccount.google.com/permissions.
We do not sell, share, transfer, or use Google user data for advertising, and no human reads it.

Wallpaper Calendar's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Purchases

Pro purchases are processed by Stripe; we never see your card details. The email you enter at checkout is used only to issue your license key, which itself is verified offline on your device — the app never contacts a license server.

Other optional connections

Features you can enable make direct requests from your device to: Open-Meteo (weather, sends your chosen city's coordinates), iCal feed URLs you paste, Anthropic (AI assistant, only if you provide your own API key), and this website (update checks send no personal data). None of these are active until you turn the feature on.

Changes & contact

If this policy changes, the update will be posted here with a new effective date. Questions: dcgautosbc@gmail.com.
