Privacy policy
Effective date: November 9, 2026. This policy describes the Mythweaver desktop companion (version 1.2.6) and this informational website.
In brief: Mythweaver is a local-first personal roleplay tool. Google Gmail access is limited to sending emails after account authorization. Mythweaver does not request access to read, modify, or delete Gmail messages.
1. What Mythweaver handles
The desktop application locally stores player-configured character biographies, settings, recorded eligible roleplay dialogue and emotes, encounter history, session reviews, and related metadata. Out-of-character messages marked [OOC] are excluded from in-character memory. Private whisper histories are kept separate from public interactions and isolated by character and correspondent.
2. Gmail access and use
With the user's authorization, Mythweaver uses the Google Gmail API scope https://www.googleapis.com/auth/gmail.send solely to send generated roleplay-session review emails to its configured recipient. The app does not request Gmail inbox-reading, mailbox-modification, or message-deletion scopes. Emails sent through the Gmail API may also appear in the authorized user's Gmail Sent folder.
OAuth client configuration and tokens are stored locally on the Windows computer under the user's application-data folder, not submitted to this website. The user can disconnect or revoke Google's access through their Google Account.
3. Optional Gemini processing
When the user explicitly enables automatic AI reviews in Mythweaver, eligible saved in-character and observed roleplay excerpts are transmitted to Google's Gemini service for summarization and analysis. Inclusion of captured private whisper content requires a separate, explicit opt-in; without it, private whispers are excluded from automatic cloud analysis and review emails. Reviews may contain descriptions of encounters and proposed narrative developments, but proposed changes never become character canon without explicit approval inside Mythweaver.
The Gemini service processes submitted content subject to Google's applicable service terms and privacy practices. Mythweaver does not upload roleplay excerpts to Gemini merely because the public website was visited.
4. Local storage and backups
Mythweaver saves persistent application data locally in the user's chosen data directory. Users may independently synchronize that directory to their own Google Drive backup folder. This synchronization is controlled by the user's backup software and is not performed using Mythweaver's Gmail authorization. Users are responsible for securing cloud backup access. Automated encrypted OAuth-token backup is not a feature of version 1.2.6.
5. Website data
This site provides static information only. It has no account registration, forms, embedded analytics, advertising trackers, or client-side scripts. The hosting provider, Cloudflare, may process ordinary technical request information (such as IP addresses and request logs) to deliver and protect the website in accordance with its own policies.
6. Sharing, retention, and control
Mythweaver does not sell user information or use Gmail API data for advertising. User-enabled cloud processing and email delivery necessarily send selected information to Google services as described above. Recorded roleplay histories and review records remain under the user's control in local application data and any backups they maintain. Users can disable optional cloud analysis and Gmail delivery, delete their local data, and revoke Google authorization. Removing local copies does not automatically erase existing emails, external service records, or independently synchronized backups.
7. Google API data policy
Mythweaver's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including applicable Limited Use requirements.
8. Changes and contact
This policy will be updated if Mythweaver's information practices materially change. For questions about these practices, contact mdg.sovereign@gmail.com.
