NurtureTech

Lifestyle logbooks, not a food database

We build lifestyle logbooks. A new plate can be estimated from a photo, a short description or voice with your own Google Gemini API key (BYOK). Saved meals and fluids stay on the device and do not need AI. Coaching is automatically generated lifestyle information — not medical advice.

A nutrition studio, not a data mill

NurtureTech ApS (under stiftelse) is a Danish studio for lifestyle logbooks, fasting as a lifestyle tool, and privacy-first metric tracking. We ship focused products that help people understand what they eat. Coaching in our apps is automatically generated lifestyle information — not medical advice.

Saved meals, fluids and history stay 100% locally on your device. A new plate estimate from photo, text or voice requires your own free Google Gemini API key (BYOK) and consent. That specific input is sent encrypted through our memory-only serverless proxy to Google Gemini and is not persisted on NurtureTech servers. There is no free-text food database as the primary path. No ad networks.

Two products. One standard for clarity and care.

Nutrition & coaching

Ketora

A personal logbook with nutrient estimates. A new plate can be estimated from photo, text or voice with your own Gemini key (BYOK). Saved meals and fluids stay on the device. Fasting is a timer and lifestyle information — not ketosis measurement.

Three tracks, stated plainly

A new plate estimate is optional AI. Saved meals and fluids are local. Coaching is lifestyle information — not medical advice.

Can I log food without AI?

Yes, once a plate is saved under My meals. Fluids, fasting, weight and activity are always local. A new plate estimate uses Gemini and your key. There is no free-text food database as the primary path.

Is this a medical device / does it measure ketosis?

No. Lifestyle logbook and estimates only. No ketosis measurement, diagnosis or treatment.

Where does a photo or meal description go?
