Privacy Policy
This policy describes how 3SL Newsletter Digest (the "app"), a personal-use tool operated by 3SL Studios, accesses, uses, stores, shares and deletes data, including data received from Google APIs.
Google API Services User Data Policy
3SL Newsletter Digest's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Who uses the app
The app is used only by its owner. There are no other users, no public sign-up and no accounts for anyone else.
Google user data the app accesses
- Gmail messages from newsletter senders. The app has read-only access to the owner's Gmail so that it can read these newsletters. Google's read-only permission technically covers the whole mailbox; the app uses it only for messages from newsletter senders.
- The ability to send email to the owner's own address. The app uses this only to send the daily digest to the owner. It does not send email to anyone else.
The app does not request access to any other Google data.
How the data is used
Solely to generate the owner's personal digest and audio summary: finding newsletters, extracting and grouping the article links they contain, writing the digest and emailing it to the owner.
- It is not used for advertising.
- It is not sold, and it is not transferred to advertising platforms, data brokers or information resellers.
- It is not used to train AI or machine-learning models.
- It is not used to determine creditworthiness or for lending.
Processing by service providers
To produce the digest, newsletter text may be sent to an AI model provider (Anthropic) and to a text-to-speech provider. They receive it solely to produce the digest and audio summary for the owner. The data is not shared with anyone else.
Storage and security
Processed data is stored on the owner's private server, along with the access credentials (OAuth tokens) that let the app run its daily job. Data travels between the app, Google and the providers above over encrypted (HTTPS) connections.
Retention and deletion
Processed data is kept only as long as the owner wants it for the digest. The owner can delete it at any time.
Revoking access
Access to the Google account can be revoked at any time at https://myaccount.google.com/permissions. Once access is revoked, the app can no longer read or send email.
Changes to this policy
If this policy changes, the effective date above will change. The app will not use Google user data in a new way without first updating this policy.
