Effective date: June 9, 2026
App: Mindember (iOS, com.darashkou.mindember)

1. Who We Are
Mindember is a personal voice-note application developed and operated by Andrei Darashkou ("we", "us"). This policy describes what personal data we collect when you use the Mindember iOS app, how we use it, and what rights you have.
2. What Data We Collect and Why
2.1 Account Information
When you sign in with Apple or Google, we receive and store:
| Data | Source | Why |
|---|---|---|
| Email address | Apple / Google Sign-In | Uniquely identifies your account; used for account management |
| Display name | Apple / Google Sign-In | Shown in the app interface |
| Provider user ID (Apple or Google sub) | Apple / Google Sign-In | Links your social login to your Mindember account |
This data is linked to your account and stored on our server for as long as your account exists.
2.2 Voice Recordings (Audio Data)
When you record a voice note, the audio file (.m4a) is uploaded from your device to our server and immediately forwarded to OpenAI for transcription (see Section 4). We do not store the raw audio file — it is processed and deleted from our server. The resulting transcript text is stored in our database (see 2.3).
Audio is used solely to produce the text of your note. We do not use your voice recordings for any other purpose.
2.3 Note Content
For each note, we store in our database (PostgreSQL):
| Field | Description |
|---|---|
| Raw transcript | The verbatim text returned by OpenAI Whisper from your audio |
| AI-generated title | A short one-line summary produced by the OpenAI LLM |
| AI-generated body | An organised markdown version of your note, produced by the OpenAI LLM |
| Note type | A category assigned by the LLM from a fixed built-in set (e.g. "idea", "reminder") |
| Status | Active / done / rejected — set by you |
| Reminder date | If you mention a time in your note, the LLM extracts it as a reminder |
| Creation timestamp | When the note was saved |
| Audio duration | Length of the recording in seconds (used for quota tracking) |
Notes are stored indefinitely until you delete individual notes or your entire account.
2.4 Push Notification Tokens
To deliver reminder notifications, we store your device's APNs (Apple Push Notification service) token on our server. This token is associated with your account and is used exclusively to send you reminders for notes that have a reminder date set. It is deleted when you log out or delete your account.
2.5 Audio Usage Metrics
We store a record of the duration charged for each note upload (in seconds). This data is used solely to enforce the monthly voice-minute quota included in your plan. It does not include the audio content itself.
3. Data We Do Not Collect
- We do not collect location data.
- We do not collect contacts or address book data.
- We do not serve advertising and do not collect advertising identifiers.
- We do not track you across other apps or websites (
NSPrivacyTracking = false). - We do not sell your data to any third party.
4. Third-Party Data Processor: OpenAI
To transcribe audio and classify notes, we use services provided by OpenAI, L.L.C.:
- Whisper (
/v1/audio/transcriptions): your audio file is sent to OpenAI's API and transcribed into text. OpenAI receives the raw audio. - GPT (Chat Completions API): the transcript text is sent to OpenAI's API. OpenAI returns a JSON object containing the note title, body, type, and optional reminder.
OpenAI acts as a data processor on our behalf. According to OpenAI's API data usage policies, data submitted through the API is not used to train OpenAI's models by default.
We encourage you to review OpenAI's privacy policy: https://openai.com/policies/privacy-policy/
No other third parties receive your personal data.
5. Data Storage and Security
Your data is stored on a cloud server hosted on Railway (Railway Corp.), reachable at https://mindember.org. Railway acts as our infrastructure and hosting provider. All communication between the app and our server uses HTTPS/TLS. Authentication uses industry-standard JWT tokens; your credentials are never stored in the app — only access tokens, kept in the iOS Keychain.
We take reasonable technical measures to protect your data, but we cannot guarantee absolute security.
6. Your Rights and Data Deletion
You have the right to:
- Access your notes through the app at any time.
- Delete individual notes via the note detail screen.
- Delete your account and all associated data directly in the app: go to Settings → Delete Account, confirm the action, and your account, all notes, push tokens, refresh tokens, and audio-usage records will be permanently and irreversibly deleted from our server. This corresponds to
DELETE /api/users/me, which cascades all your data.
There is no waiting period — deletion is immediate and cannot be undone.
If you have questions or requests regarding your personal data that cannot be addressed through the app, contact us at [email protected].
7. Children
Mindember is not directed at children under 13. We do not knowingly collect personal data from children under 13.
8. Changes to This Policy
If we make material changes to this policy, we will update the effective date at the top of this document. Continued use of the app after the updated date constitutes acceptance of the revised policy.
