Foundry Companion App: Privacy Policy
Last Updated: April 2, 2026
1. Introduction
Welcome to the Foundry Companion App. We are committed to protecting your privacy.
This policy explains how we handle data when you use our mobile application and our associated Foundry VTT module.
Our guiding principle is Data Minimization: we only process the data strictly necessary to provide a functional character sheet experience.
2. Data Collection
The Foundry Companion App is a client-side tool.
- Character Data:
All character stats, spells, and items are stored on your own self-hosted Foundry VTT server or your GM’s server. - No Data Storage:
We do not own, store, or have access to your character data. The connection is a direct link between your mobile device and the Foundry VTT server URL you provide.
3. Data We Collect and How We Use It
- Local Storage:
We use Capacitor Preferences (local storage) on your device to remember your Server URL, Actor ID, and UI preferences (like Pinned Tabs). This data stays on your device. - Authentication Data:
To connect to Foundry, you enter a username and password. This is sent directly to your Foundry server via a secure socket. We never see or store your passwords. - Patreon Integration:
If you use the premium version of the module, Foundry VTT verifies your subscription status via the Patreon API. We do not receive your Patreon information, nor credit card or billing details. - Tally.so:
We collect names and email addresses via Tally.so for the sole purpose of distributing beta testing invites and project updates. This data is never shared or sold. You can unsubscribe at any time by contacting us.
4. Third-Party Services
Our app interacts with the following third-party services:
- Patreon:
Used for subscription verification. Patreon Privacy Policy - Google Play Services / Apple App Store:
Used for app distribution and (eventual) processing in-app purchases. - Socket.io:
Used for the technical real-time connection between the app and the server. - Foundry VTT:
Used for the core functionality of the app, which connects to your Foundry VTT server.
