In short: we collect what we need to help you meet people near you and to keep knock safe. We never sell your data, show your exact location, or read your chats to rank you. You can download or delete everything at any time.
Who we are
knock is an invite-only dating app for adults in India, run by Knock Support ("we", "us"). We decide how your personal data is used, so we are the data fiduciary under India's Digital Personal Data Protection Act, 2023 (DPDP Act).
What we collect
We collect the information you give us and a small amount that knock creates as you use it:
| Data | Details |
|---|---|
| Mobile number | Your Indian mobile number, used to sign you in with a one-time code. |
| Birthday | Used to confirm you are 18 or older. We show your age, never the date, and it is locked once you confirm it. |
| Profile | Your name, gender and who you want to see, what you're looking for, interests, languages, bio and prompts. |
| Photos | The photos you add. We remove hidden metadata, including GPS location, and review each photo before it goes live. |
| Approximate area | Your location, rounded to about 1 km. We do not keep a location history. |
| Activity | Who you knock on or pass, your matches, and the order and context in which profiles were shown to you. |
| Messages | Messages you send and receive in matched chats. They are encrypted when stored. |
| Safety records | Reports you file (reason, details and the match), people you block, and our moderation decisions on photos and reports. |
| Device and consents | A push-notification token for your device, and a record of the consents you give or withdraw. |
Why we use it
- To run knock: sign you in, build your profile, show you people you're likely to match with, and let you chat once you both knock.
- To keep knock safe: check ages, review photos, handle reports, and act on accounts that break our Community Guidelines.
- To improve knock: understand how features are used, with data that can't identify you.
We do not sell your data, use it for third-party advertising, or read your chats to rank you.
Your choices
Some uses need your consent, and you can change each one at any time in Settings:
- Service (required): the basics needed to run your account. Withdrawing this means deleting your account.
- Personalised ranking: using your activity to tailor who you see.
- Date feedback for model training: using feedback you choose to give after a date to improve matching.
- Notifications: alerts when a door opens or someone messages you.
Who we share it with
We share data only with service providers who process it for us, under contract, to run knock:
| Provider | What they do |
|---|---|
| Amazon Web Services | Runs our app servers (Mumbai, India). |
| Neon | Hosts our database (Singapore). |
| Upstash | Caching and real-time chat delivery (Singapore). |
| Cloudflare | Network security, content delivery and photo storage. |
| Google Firebase | Sends sign-in codes and push notifications. |
Other people on knock see only your profile and photos, and only if you match each other's preferences. We may disclose data when the law requires it, for example to respond to a valid legal order.
Where it's stored
Our app servers are in India. Some data, including our database, is stored in Singapore. We will update this policy if we move that storage to India.
How long we keep it
We keep your data only as long as we need it to run knock for you:
| Data | Kept for |
|---|---|
| Chats | 90 days after a match closes, then deleted, unless a report about that conversation is still open. Then we keep it until the report is resolved. |
| Profile, photos and preferences | Until you delete your account. |
| Sign-in codes | A few minutes, then deleted. |
| Activity logs | Kept in a form that can't identify you, and excluded from model training. |
When you delete your account, we immediately erase your profile, photos, preferences, the messages you sent, the data we derived about you, and your sign-in details. Messages you received are deleted with the conversation within 90 days.
Your rights
Under the DPDP Act you can:
- Access your data: download everything we hold about you from Settings.
- Correct it: edit your profile at any time.
- Erase it: delete your account from Settings, or see Delete your account to do it without the app.
- Withdraw consent for any optional use, in Settings.
- Complain to our grievance officer (below), and then to the Data Protection Board of India.
Children
knock is only for adults aged 18 or older. Everyone confirms their birthday and that they are 18 or older before they can see anyone. If we learn that someone under 18 has an account, we close it.
