Keepwarden

A task app with an AI assistant — built so that you never have to trust us with your data.

What it does

• Your tasks, projects and notes, in lists you shape: deadlines, repeats, steps, labels, fields of your own, and saved views such as “Now”.
• An assistant you talk to. Tell it what you need in your own words. It files tasks, sorts your inbox, and plans your day — and every change it suggests is a card you approve. Nothing changes on its own.
• Your calendar, if you want it. Connect Google Calendar and the assistant can see your schedule, tell you when you are free, and plan tasks around your events. Adding an event is always a card you approve first.
• Capture by voice with Siri, straight into your inbox.
• Bring your tasks in from the task app you use today.

Private by design — on Witbitz

Keepwarden is built on Witbitz, a platform for apps where people and AI assistants work together, and its security is Witbitz's. How Witbitz protects your data is explained, and made checkable, on their site. How Keepwarden uses it:

• Your lists live in your own room, stored sealed under a key that stays on your device. The storage holds only encrypted bytes; no one can read them there — not us, and not Witbitz. We run no server that stores your data.
• The assistant reads what your question needs, and where that happens depends on your room:
  • In a standard room, the answer comes from GPT-5.5 by OpenAI, so OpenAI can read the text of that turn. The request reaches OpenAI from Witbitz, not from you — not your account, your email or your address — so it has no way to tell the text is yours, unless the text itself says so.
  • In a confidential room, the answer comes from an open-weights model running inside a verified hardware enclave. No one has access to your content there — not us, not Witbitz, not a model company — and your device verifies the enclave before it sends anything.
• Your Google Calendar connection is held in such an enclave; its tokens never reach your device or us.

The Privacy Policy has the details.

Google user data

Keepwarden uses Google Calendar data only to show you your schedule, to let the assistant plan around it, and to add or change events you approve. Keepwarden's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
