Who we are

M IN is provided by Rentuku Technologies LLC, a Connecticut (United States) limited liability company ("we", "us"). We are the Data Fiduciary for the personal data described here. This policy covers the M IN app on iPhone and Android and the websites sayim.in and min.sayim.in. Our Data Protection contact is support@sayim.in.

What we collect and why

Each item below lists the personal data and the specified purpose we use it for. We don't use it for anything else without asking you.

1. Account

Data: name, email address or phone number, password, verification details that confirm you are a real person, and account-security records (devices you signed in from, sign-in times, approximate sign-in location).
Purpose: to create and secure your account, verify that you are a real adult, and warn you about sign-ins that weren't you.

2. Profile

Data: display name, photos, a short bio, interests, and your general area (for example "Gachibowli").
Purpose: to show other verified users who they'd be meeting. Photos pass through moderation, sometimes by a person, before they're shown.

3. Plans

Data: plans you host and join: title, time, place, spots, meeting spot if set, who asked to join and who was accepted.
Purpose: to show plans to people nearby and to run the plan and its chat. The list of who joined is visible only inside the plan.

4. Messages (encrypted)

Data: plan chats and private conversations, including voice notes, photos, reactions and Secret Messages, are encrypted in transit and in storage. M IN manages the recovery keys so your history returns when you sign in on another device; this is not end-to-end encryption, and authorised M IN services can access message content, for example to act on a report or when the law requires it. Our servers hold messages as chat history for the people in that chat until they are deleted, the account is deleted, or a Secret Message vanishes after it has been seen. We also keep who a message is for, when it was sent, and its size.
Purpose: delivery. If you report a message, your phone sends us the readable text of that message, with your consent, so we can act on the report.

5. Approximate location

Data: your location rounded to the neighbourhood level, never exact coordinates, and only while you use the app. Live location, when you choose to share it in a plan chat, goes encrypted to the people in that chat for the time you pick, and is erased within about an hour after the share ends.
Purpose: to show you plans nearby, and to help people in a plan find each other on the day. You can turn location off in your phone settings and search by area instead.

6. Nearby alerts (optional)

Data: only if you turn on "Plans and deals near you" in Notifications: a geohash cell of about 5 km square that contains your approximate location, your city and area name, and when you last opened the app. These are kept in a record of nearby areas (nearbyAreas). We never store your exact location or coordinates for this.
Purpose: to send you "near you" notifications when someone in your area posts a plan or a deal goes live, and to work out an anonymous count of how many people near you opened M IN this week. That count is rounded down, never linked to anyone, and never shown when it is below 5. The record is deleted when you turn nearby alerts off or delete your account.

7. Device and diagnostic data

Data: device model, OS version, app version and recent technical logs, attached only when you send a support ticket or shake to report. You see the attachment before you send it and can remove it. We do not run usage analytics.
Crash reports: if the app crashes, it can send an anonymous crash report — the stack trace, device model, OS version, app version and a random installation identifier. Crash reports never contain your name, email, messages, photos or plans, and we never attach your account to them. They are on by default in the released app so we can fix what breaks; you can turn them off any time in You → Crash reports, which also discards any report not yet sent.
Purpose: to work out what went wrong and fix it.

8. Support and grievance correspondence

Data: emails, tickets and reports you send us, and our replies.
Purpose: to help you, act on reports, and keep the record the law requires.

Consent

We process your personal data on the basis of your consent, which you give in the app when you create your account and, for location, when you allow the permission on your phone. Consent is free, specific, informed and unconditional, and you can withdraw it as easily as you gave it:

• Withdraw all consent: delete your account in the app (You → Account → Delete account), or ask us on the delete your account page without installing anything. Processing stops and your data is erased as set out under retention below, except where we must keep something by law. That page itemises what is deleted and the little that is kept.
• Withdraw location consent: turn off location for M IN in your phone's settings.
• Withdraw consent for nearby alerts: turn off "Plans and deals near you" in Notifications. Your nearby-area record is deleted.

Where the law lets us process without consent for certain legitimate uses, such as responding to a legal order or a medical emergency, we will do only what that use requires.

Who we share with

• Other users see your profile, the plans you host and, inside a plan, that you're in it. People you block see none of it.
• Data Processors who run our infrastructure on our instructions and may not use your data for their own purposes: our cloud hosting, database, file storage and sign-in provider (which also delivers push notifications, checks that the app is genuine and, if you leave it on, receives crash reports); an automated image-screening service for profile and plan photos (it checks for nudity, violence, a visible face and whether a photo is already in use — it does not identify who you are); our email delivery provider; and the phone's map service (Google Maps on Android, Apple Maps on iOS), which draws maps and looks up place names and place searches when you pick, send or view a location or live location (it sees your device's IP address, the map area or place requested and your search text, nothing about your account). None of them can read your encrypted messages. Our AI provider (Anthropic PBC) receives only the text of chats with an M IN Buddy, to write the Buddy's reply.
• Authorities, where the law requires or to prevent serious harm. We share only what we have; encrypted message contents are not something we hold in readable form.

We do not sell personal data, we do not show advertising, and we do not share data with advertisers or data brokers.

M IN Buddies (automated accounts)

Some accounts on M IN are Buddies: automated accounts we run to keep a new person company in their first days and point them at real plans nearby. They are not people. Every Buddy is marked everywhere it appears — a glowing badge on its picture, an "M IN Buddy" label beside its name, a handle ending in _buddy, and a line at the top of its chat — its picture is an illustration, and if you ask it whether it's real it says it's automated. A Buddy never meets anyone and never suggests meeting; it only helps you find or start a plan with real people.

Data: a Buddy may wave at you once after you finish setting up your account if you haven't posted or joined a plan yet, or when you tap "Say hi to an M IN Buddy". The text you type in a Buddy chat is read by our systems to write the reply, and is sent for that purpose to our AI provider (Anthropic PBC, USA), which processes it on our instructions and does not use it to train its models. We also keep how many replies were sent each day, so the feature has a cost cap. Only Buddy chats work this way: chats with real people are never read to generate replies.
Purpose: to make the app useful before you know anyone on it. You can block a Buddy like any account, and it will not message you again. Buddy chat records are deleted with your account.

Beta programme

If you sign up at sayim.in/beta to test new versions, we collect your name, email, date of birth, city and state, whether you use Android or iPhone, and the language you chose. We use them only to check you're 18 or older and in India, to email you about every beta version (test builds, what to try, short questions) until you unsubscribe, and to see which phones and cities our testers cover. Your email goes to Apple (TestFlight) or Google (Play testing) only when we invite you to a build. Every beta email has a one-click unsubscribe link; after that we don't email you again unless you sign up again. To have your beta details deleted, reply "STOP" to any beta email or write to support@sayim.in, and we delete them within 30 days. Beta details are kept separately from any M IN account you have.

Places that apply on sayim.in/promote

If you apply to list a café, restaurant, turf or venue at sayim.in/promote, we collect the business details you enter (name, category, address, area, city and, if you give it, location), the offer and its terms, the photos of the place you upload, and the contact person's name, email and phone number. We use them only to review the application, to call or email you about it, and, once you have agreed the deal with us, to show the place and its offer in the app. To have an application deleted, write to support@sayim.in.

Where data is kept

Your data is stored and processed on servers located in India. Some processors (for example push-notification and email delivery, and our team when working from outside India) may process limited data outside India. Such transfers are made only to countries not restricted by the Central Government under the Act, and with the same protections described here.

If you are in California, the EU or the UK

M IN is built for India, but Rentuku Technologies LLC is a US company and some of you use it from elsewhere, so this section says how other privacy laws apply.

• California (CCPA/CPRA): we do not sell your personal information and we do not share it for cross-context behavioural advertising, and have not done so in the past 12 months. We use no advertising cookies or trackers. You have the right to know what we collect (this policy and You → Privacy → Request my data), to delete it (in the app, or from the web), to correct it, and not to be treated differently for exercising those rights. An authorised agent may make a request for you; we will verify it with you first. We do not knowingly collect information from anyone under 18.
• EU and UK (GDPR): Rentuku Technologies LLC is the controller. We process your data to provide the service you asked for (contract), with your consent where we ask for it (location, notifications, crash reports, photos), and in our legitimate interest in keeping the community safe (moderation, security records), which you may object to. Your data is stored on servers in India; where it moves across borders we rely on standard contractual clauses. You have the rights of access, rectification, erasure, restriction, portability and objection described above, and the right to complain to your local supervisory authority. Contact for all of this: support@sayim.in.

How long we keep it

• Account, profile and plans: while your account exists. When you delete your account, your profile, photos, plans, preferences, keys and every other record we hold about you are erased straight away — the deletion runs within minutes, not weeks. The only thing kept is a minimal registration record (the email address, username, phone number if you gave one, how you signed in, and when the account was created and deleted), which rule 3(1)(h) of the IT Rules, 2021 requires us to retain for 180 days after an account is closed. It is locked away, used for nothing else, erased automatically when the 180 days are up, and nobody can register your old username while it exists.
• Encrypted messages: kept as encrypted chat history for the people in that chat until you delete them or your account is deleted. Secret Messages are removed once the recipient has seen them and left the chat, and at the latest 24 hours after they were seen. Messages sent under the older chat timer (24 hours, 7 days or 90 days) are deleted when it runs out.
• Approximate location: replaced each time you open the app; not kept as a history.
• Nearby alerts: the nearby-area record is updated when you open the app, not kept as a history, and deleted when you turn nearby alerts off or delete your account.
• Live location: erased within about an hour after the share ends.
• Account-security records: erased after 90 days.
• Support tickets and diagnostics: erased 12 months after the ticket is closed, except safety reports, which are kept under the next point.
• Reports, grievances and moderation decisions: as long as needed to enforce our guidelines and meet the record-keeping required under the IT Rules, 2021, including after the accounts involved are deleted.
• If you don't use M IN for 3 years and the law no longer requires us to keep your data, we erase it.

Your rights as a Data Principal

• Access: a summary of the personal data we hold about you, how we process it, and who we've shared it with. You → Privacy → Request my data, or email us. We reply within 30 days.
• Correction and completion: edit your profile any time in the app, or ask us to correct anything else.
• Erasure: delete your account in the app, or ask us from the web. We erase your data unless a law requires us to keep it.
• Withdraw consent: as described above.
• Grievance redressal: write to our Grievance Officer at support@sayim.in. We acknowledge within 24 hours and resolve within 15 days.
• Nominate: you can name someone to exercise these rights for you if you die or become incapacitated. Email support@sayim.in with their name and contact details, and we'll record it.

You also have duties under the Act: give us accurate information, don't impersonate anyone, and don't file false or frivolous complaints.

Age

M IN is for adults. You must be 18 or older to create an account. We don't knowingly collect personal data from anyone under 18; if we learn we have, we delete the account. If you believe someone under 18 is using M IN, tell us at support@sayim.in.

Security

We encrypt messages and media in transit and in storage, encrypt everything else in transit and at rest, and use two-step sign-in and access controls so that only the few people who need to see support and moderation data can. If a breach affects your personal data, we'll tell you and the Data Protection Board of India as the Act requires.

Changes to this policy

If we change this policy in a way that matters, we'll tell you in the app before it takes effect. The date at the top always shows the current version.

Contact and complaints

Please contact us first; most things are sorted within a few days. If you're not satisfied with how we've handled a grievance, or we haven't responded within the time the law allows, you have the right to complain to the Data Protection Board of India, the body set up under the Digital Personal Data Protection Act, 2023.
