Privacy & data
What Bertram accesses, what it keeps, and what it never does.
Bertram is built to help with your email without hoarding it. Your mail is read from your provider and used to do the job you asked for — summarize, draft, prioritize, schedule — and not for anything else.
What Bertram stores
Email content is fetched from your provider on demand and is not stored permanently — there is no separate archive of your mailbox. What Bertram does keep is the things you create inside it: tasks, follow-up tracking, contact notes, drafts in progress, and your daily briefings — so they are there when you come back.
What the AI sees
When you use an AI feature, the relevant message content is sent to Anthropic's Claude, the result comes back, and Bertram shows it to you. Your email is never used to train AI models — asking for a summary feeds you an answer, not a training set.
What Bertram never does
- Send an email, accept a meeting, or change your calendar without your action.
- Use your mail to train AI models.
- Sell or share your email content with third parties for advertising.
Staying in control
Access was granted through OAuth and can be withdrawn whenever you like — from Settings or directly in your Google or Microsoft account. Disconnecting stops Bertram reading that mailbox, full stop. And when you contact support, you never need to paste email contents — describing the behavior is enough.
