Privacy Policy
QuantumPair (quantumpair.date) is a place for virtual dates between two people who live apart. It is built so that what you share with your partner stays between the two of you. This policy says what the service stores, why, and for how long.
Who is responsible
QuantumPair is run by Dmitriy Sosnovich. For anything about your data, write to dmitriy.sosnovich@gmail.com.
What stays between you and your partner
- Notes, love capsules, Polaroids and your shared plans (bucket list, dinner plans) are encrypted on your device with a key that only your two devices hold (X25519 and ChaCha20-Poly1305). The server only ever passes them on as ciphertext it cannot read. They are kept on your devices, in the browser's storage.
- Video and sound go directly between your two devices (WebRTC), encrypted (DTLS-SRTP). When a direct connection is impossible, they pass through our relay server, still encrypted. Calls are never recorded.
- Your local time zone is sent to your partner so the room can show both clocks. It is not stored on the server.
What the server keeps
- While you are in a room: your connection's IP address and a reference to the room, a short code derived from the room's PIN that does not reveal it. This is kept in memory only, so that abuse can be stopped, and it is gone when you leave.
- Each date: when both partners were together, from start to end, under the room's reference. No names, no PIN and no content are kept. This counts how much the service is used.
- If you sign in:
- your account ID;
- your email address, once it is verified;
- the display name you choose;
- when the account was created and last used.
- Blocked addresses: when an IP address is blocked for abuse, the address, the reason and the duration.
The website keeps no access logs. The server's technical logs do not contain room PINs, names or anything you write.
Signing in
Sign-in is provided by Google Firebase Authentication. You can sign in with Google or with a one-time link sent by email. Google processes your sign-in under its own privacy policy and tells us only who you are: your account ID and email. QuantumPair never sees your Google password.
Who else is involved
- DigitalOcean hosts the server in Frankfurt, Germany (EU).
- Google Firebase handles sign-in.
- Ollama (ollama.com) writes new Intimacy Deck questions, only when you ask for them. It receives the deck's theme and your language, nothing you or your partner wrote.
There are no advertisements, no analytics or tracking scripts, and no selling of data.
Cookies and storage on your device
QuantumPair sets no cookies. It uses your browser's local storage for:
- your encryption keys and encrypted keepsakes;
- your sign-in session;
- your language;
- your partner's time zone.
Clearing the site's data removes them from that device.
How long data is kept
- Account data is kept until you ask for it to be deleted.
- The database is backed up every night, encrypted, and backups are kept for 14 days. After you delete your account, it disappears from backups within those 14 days.
- Records of dates contain no personal data and are kept while the service runs.
Your rights
You can ask to see, correct or delete your data, and to object to its use, by writing to the address above. You can also complain to your data protection authority. Your display name can be changed in the app, under Profile. Deleting an account in the app itself is not available yet; until it is, write to us and it will be deleted.
Children
QuantumPair is meant for people aged 16 and over.
Changes
If this policy changes, the new version is published here with a new date. Important changes are announced in the app.
