Bring your own key

Your key, your photographs.

The coach can run on Aperi's own key, or on an API key you get yourself from Google, Anthropic or OpenAI. Your own key stays on your phone and the photo goes straight to the provider you chose; Aperi's key stays on our server, and the photo passes through a relay that keeps none of it. This page says, in each provider's own words, what happens to it there.

Where your photograph goes

Checked against the providers' published terms on .

Google Gemini API

Get a key: console at aistudio.google.com

Used for training?

Paid tier

Not used for training

“Google doesn't use your prompts (including associated system instructions, cached content, and files such as images, videos, or documents) or responses to improve our products.”

Logged only to detect violations of their prohibited-use policy.

Unpaid (free) tier

Used to improve Google's products

Google “uses the content you submit to the Services and any generated responses to provide, improve, and develop Google products and services”, and “human reviewers may read, annotate, and process your API input and output”.

Users in the European Economic Area, Switzerland or the United Kingdom get the paid-tier terms on the free tier too.

Terms last updated .

If you use a free-tier Gemini key, your photographs can be read by people at Google. Turn on billing, or choose another provider, if that is not acceptable to you.

Anthropic Claude API

Aperi coach (our key)

No key to get: choose Aperi coach in the app.

Used for training?

Not used for training

Runs on the OpenAI API under the same terms as above, on a key we hold. Our relay meters usage and forwards the frame; it never stores your photograph, your question or the reply, and the usage rows it keeps are pruned after 90 days. We will never enable a data-sharing or training option on our key, and we will never train models of our own on your photographs.

What Aperi itself does

  • Your own key is stored on the phone (in the Keychain on iPhone) and sent only to its own provider's API, never to us.
  • The coach receives the live-view frame or the last shot plus the camera's settings as text, never a screenshot of the app.
  • Conversation history keeps only the most recent frame as an image.
  • Nothing is uploaded until you press send or ask.

Which to choose

Aperi coach for zero setup and a few free turns a day; your own key for unlimited use at the provider's prices; the Gemini free tier only if you are fine with the terms above.
