Recipes on your iPhone

Recipes you choose to save are stored locally
in the app’s database on your iPhone.
The saved recipe library is not automatically
synchronized to a cloud account.
However, recipe content may also be processed
or temporarily retained by the AI services
described below when you generate or refine it.
Device backups may preserve local app data.

AI recipe requests

When you request a new recipe or modify an
existing one, prmpt. sends the relevant text
to its Supabase backend and to OpenAI for
AI processing. This can include your request,
the current recipe’s ingredients and
instructions, and dietary restrictions or
excluded ingredients you have provided.
OpenAI generates the response that appears
in the app.

Voice input

prmpt. uses Apple’s Speech framework to
convert spoken requests into text.
Speech recognition may involve Apple’s
servers. The app does not create a saved
recording file from your microphone input
or send raw microphone audio through its
recipe generation service.
The resulting text may be submitted
automatically when you finish speaking.

Anonymous identification

prmpt. does not require your name, email
address or a password to generate recipes.
Its backend uses a persistent pseudonymous
identifier to manage requests, usage
allowances and technical reliability.
This identifier is not the same as
complete anonymity.

Server records

The Supabase backend currently stores
generated responses and technical request
records. These may include recipe content,
user identifiers, timestamps, request
status and usage counts.
Some records are used to prevent duplicate
processing or charges when a request is
retried. Completed response records do not
currently have a verified automatic deletion
schedule.

Third-party services

Supabase provides authentication and
backend infrastructure. OpenAI processes
cooking requests and generates responses.
Apple provides speech recognition when you
use the microphone. These providers may
process technical information and retain
operational or security records under their
applicable policies. prmpt. does not
currently use advertising or behavioral
analytics systems identified in the
audited implementation.

Data retention and deletion

Saved recipes remain on your device until
you remove them or delete the app’s local
data. Server records may remain after the
app is deleted. A comprehensive automatic
deletion schedule for completed server
responses has not yet been implemented.
To request access to, correction of or
deletion of personal data, contact
barbara.k.prokop@gmail.com.
Because the backend uses anonymous accounts,
additional verification may be needed
before account-specific data can be deleted.
Provider logs and backups may have separate
retention periods.

Your choices

You can type instead of speaking and can
revoke microphone or speech-recognition
access in iPhone Settings. You can remove
recipes from your local saved library.
Avoid including unnecessary personal or
sensitive information in cooking requests.
Revoking permissions or deleting the app
does not automatically remove information
already processed by external providers.

Your rights

Depending on applicable data protection law,
you may have rights to request access,
correction, deletion, restriction or
portability of your personal data, and
to object to certain processing.
You may also contact the relevant
data protection supervisory authority.
