Who we are
Prochi is a personal relationship memory app built to help you remember the people you meet. It is operated by 1801 Partnerships, based in the United Kingdom.
What data we collect and why
Account data
When you create an account we collect your email address and a hashed password. We use this to identify you and secure your account.
Voice recordings
When you record a voice note, the audio is sent to OpenAI's Whisper API for transcription. The audio is processed in transit and is not stored permanently by Prochi. The resulting text transcript is stored in your account.
Memory notes
The text extracted from your voice notes — including names, companies, locations, interests, and life events of people you have met — is stored in your Prochi account in our database, hosted by Supabase.
Nudges and reminders
Dates and notes you set for follow-up reminders are stored against your profile records.
Contact information
If you choose to link a person's profile to your phone's contacts, we store the phone number and email address you select. We do not access your full contacts list — you choose each contact individually.
Voice note audio log
If you enable audio playback on memories, the audio file is stored securely in Supabase Storage linked to your account.
Device information
We collect basic device and usage information for debugging purposes (device type, OS version, app version). We do not track your location or use advertising identifiers.
Who we share your data with
We use the following third-party services to operate Prochi:
Service Purpose Privacy policy Supabase Database and file storage supabase.com/privacy OpenAI Voice transcription (Whisper) and AI extraction (GPT-4o) openai.com/privacy RevenueCat Subscription management revenuecat.com/privacy Apple / Google App distribution and payment processing See their respective policies
We do not sell your personal data to anyone. We do not use your data for advertising.
The people you record memories about have not consented to being stored in Prochi. You are responsible for using the app in a way that respects their privacy and complies with applicable laws in your jurisdiction.
Voice recordings and AI processing
Your voice notes are sent to OpenAI for transcription and data extraction. OpenAI processes this data under their API terms, which include data privacy protections. By using Prochi you acknowledge that your voice recordings are processed by OpenAI.
OpenAI's API data usage policy: platform.openai.com/docs/guides/privacy
How long we keep your data
We keep your data for as long as your account is active. If you delete your account, all data associated with it — including memories, notes, nudges, audio files, and contact information — is permanently deleted within 30 days.
You can delete your account at any time from the Settings screen inside the app.
Your rights
Under UK GDPR and applicable data protection law, you have the right to:
Access — request a copy of all data we hold about you
Rectification — correct inaccurate data
Erasure — delete your account and all associated data
Portability — export your data in a machine-readable format
Restriction — ask us to stop processing your data in certain circumstances
Object — object to processing based on legitimate interests
To exercise any of these rights, email us at hello@prochi.app. We will respond within 30 days.
California residents (CPRA)
If you are a California resident, you have additional rights under the California Privacy Rights Act:
The right to know what personal information is collected about you
The right to delete your personal information
The right to correct inaccurate personal information
The right to opt out of the sale or sharing of personal information
We do not sell or share your personal information.
Voice recordings are classified as sensitive personal information under CPRA. They are used solely for transcription and are not retained after processing.
To submit a CPRA request, email hello@prochi.app.
Children
Prochi is not intended for users under the age of 16. We do not knowingly collect data from children. If you believe a child has created an account, please contact us and we will delete it.
Security
Your data is stored in Supabase with row-level security enabled, meaning each user can only access their own data. Connections are encrypted in transit using TLS. We take reasonable technical measures to protect your data but no system is completely secure.
Changes to this policy
We may update this policy from time to time. We will notify you of significant changes via email or an in-app notice. The date at the top of this page reflects the most recent update.
