A private, personal life assistant that one person, Spencer Thayne, runs on his own computer for his own use. It is not offered to the public and has no other users.
Firn helps its owner keep track of his day: his schedule, email, health, finances and projects. Its assistant, Audie, answers questions and prepares plans from the owner's own records.
Effective November 8, 2026.
With the owner's permission through Google sign-in, Firn may access:
Google data is used only to provide Firn's features to its owner, such as answering his questions about his email and schedule. It is not used for advertising, is not sold, and is not used to train general-purpose AI models.
Firn runs on the owner's own computer. Google sign-in tokens are stored there, encrypted with Windows data protection. Copies of email and calendar records that Firn reads are kept in a local database on that computer. Firn has no server of its own that holds this data.
Firn does not share Google data with anyone. When the owner asks Audie a question and has turned on cloud processing, the relevant excerpts may be sent to the AI model provider he has chosen (for example Anthropic, OpenAI, Google or DeepSeek) solely to produce that answer, under that provider's terms. The owner can turn cloud processing off so that his records are processed only on his own computer.
The owner can disconnect Google at any time from Firn's Connections page. Disconnecting revokes Firn's access at Google and deletes the stored token and, unless he chooses to keep them, the cached email and calendar records. Access can also be removed at any time at myaccount.google.com/permissions.
Firn's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
