Privacy Policy
Last updated: March 25, 2026
Collab Planner is built for Twitch streamers who want to plan and coordinate collaborations with friends. This policy explains what data we collect, why we collect it, and how you can control it.
1. Data We Collect
We collect only what is necessary to provide the service.
From Twitch OAuth
- Display name, username, and profile picture
- Twitch user ID (used to identify your account)
- Your stream history (video titles, dates, durations, games) — fetched via the Twitch API to power scheduling predictions
- Your Twitch channel color and scheduled stream segments
From Discord OAuth (optional)
- Discord username and user ID
- Access and refresh tokens — stored securely to post notifications on your behalf
- Your selected Discord server and channel IDs
Data you create
- Collab events (title, date, participants, game)
- Friend lists (Twitch usernames you choose to track)
- Personal notes you write on friend profiles
- Timezone preference
Automatically collected
- Standard server logs (IP address, user agent) retained for up to 30 days for security purposes
- We do not use analytics trackers, fingerprinting, or advertising cookies
2. How We Use Your Data
| Display name, avatar | Show your profile in the app UI |
| Stream history | Calculate your typical streaming patterns and predict scheduling overlaps with friends |
| Discord tokens | Post collab event notifications and create Discord Scheduled Events in your server |
| Friend list | Track your collaborator network and detect co-streaming signals from VOD titles |
| Collab events | Calendar display, Discord notifications, reminder scheduling |
| Timezone | Format all displayed times in your local time |
We do not sell your data, share it with advertisers, or use it to train machine learning models. Data is used solely to operate the Collab Planner service.
3. Data Storage & Security
Your data is stored in a PostgreSQL database hosted by Supabase (US region). The application is hosted on Vercel. Both services maintain SOC 2 compliance and encrypt data at rest and in transit.
OAuth tokens (Twitch, Discord) are stored encrypted in the database and are never exposed in client-side responses or logs.
4. Third-Party Services
Collab Planner integrates with the following external services:
| Twitch | Authentication, stream data, schedule data | Policy ↗ |
| Discord | Optional notifications and scheduled events | Policy ↗ |
| Supabase | Database and authentication infrastructure | Policy ↗ |
| Vercel | Application hosting and edge delivery | Policy ↗ |
Each of these services has its own privacy policy governing the data they process. We encourage you to review them.
5. Data Retention
Your data is retained for as long as you maintain an account. Specifically:
- Stream history older than 12 months may be pruned to manage storage
- Reminder records are marked as sent and retained for 90 days
- Server access logs are deleted after 30 days
- When you delete your account, all personal data is permanently deleted within 30 days
6. Your Rights
You have the right to:
- Access — request a copy of all data we hold about you
- Correction — update inaccurate data via the app settings
- Deletion — request complete account and data deletion
- Portability — request your data in a machine-readable format
- Disconnect — revoke Discord access at any time from Settings; revoke Twitch access via your Twitch account connections page
To exercise any of these rights, email privacy@deutschmark.online. We will respond within 14 days.
7. Children's Privacy
Collab Planner requires a Twitch account to use. Twitch requires users to be at least 13 years old. We do not knowingly collect data from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
8. Changes to This Policy
We may update this policy to reflect changes in the service or legal requirements. Material changes will be communicated by updating the "Last updated" date above. Continued use of the service after changes constitutes acceptance of the revised policy.
