Privacy Policy
Effective date: 7 October 2026
This Privacy Policy explains what information One Day World collects, why, how long it is kept and the choices you have. One Day World is operated by Ahmad Hussain, Srinagar, Jammu and Kashmir, India ("we", "us"). Questions can be sent to mahmedhussain@outlook.com.
1. The short version
- You can read the chat and the map without an account.
- To post, you sign in with Apple or Google and allow location access.
- We keep your city and country, never your exact location.
- Your message is public for the world day you post it, then hidden and deleted after 30 days.
- We do not sell your data, show ads or track you across other apps.
- You can delete your account inside the app at any time.
2. Information we collect
When you browse without an account
- An app-generated device identifier, used only if you report or block someone, so reports cannot be repeated endlessly and your block list works.
- Basic technical information needed to deliver content, such as your device's network address while it is connected. We do not store it.
When you sign in
- Your account identifier and email address from Apple or Google. If you use Apple's Hide My Email, we receive a private relay address instead.
- The display name you choose. We do not use the name on your Apple or Google account.
- The version of the Terms you accepted and when you accepted it.
When you post
- Your message text.
- Your city and country. Your phone rounds your location to about 11 km before sending it. Our server matches that point to the nearest town or city and stores only the city name, country and the city centre's coordinates. The rounded point is discarded and your exact position is never stored.
- The time of posting and the world day it belongs to.
Safety information
- Reports you make or receive, warnings, strikes, suspensions and bans.
- An identifier for your device, stored in scrambled (hashed) form, used to enforce bans.
- The people you block.
What we never collect: precise location, contacts, photos, microphone or camera data, browsing history, or advertising identifiers.
3. How we use information
- To run the service: show messages in the chat and on the map, and enforce the one message per day rule.
- To keep the community safe: automatically check messages before they appear, handle reports, and apply warnings, suspensions and bans.
- To respond to your requests, appeals and grievances.
- To meet legal obligations.
We process your information on the basis of your consent, which you give when you accept these terms and sign in, and where needed to comply with law. You can withdraw consent at any time by deleting your account.
4. What is public
Your display name, city, country, message and the time you posted are visible to everyone using One Day World for the world day you post. Anyone viewing the app could take a screenshot, so do not share anything you want to keep private.
5. Who processes your information
We use a small number of service providers who process data on our behalf, only to run the service:
- Cloudflare (Cloudflare, Inc.) runs our server, database and this policy website.
- Apple and Google confirm your identity when you sign in. We receive only an account identifier and email address.
- Automated moderation: message text and display names (nothing else) are checked by Llama Guard, an open model run by Cloudflare, and if that service is busy, by OpenAI's moderation service.
Our providers may store data on servers outside India. We do not sell, rent or share your information for advertising. We may disclose information if required by law or a valid legal order, or to protect someone's safety.
6. How long we keep information
| Information | Kept for |
|---|---|
| Messages | Visible for their world day, then hidden and deleted after 30 days |
| Account, display name, block list | Until you delete your account |
| Reports and strikes | Until you delete your account |
| Ban records (scrambled) | Kept after deletion if an account was banned, to stop immediate re-registration |
| Daily posting records | 30 days |
7. Your rights
Under India's Digital Personal Data Protection Act, 2023 and other applicable laws, you may:
- Access the information we hold about you.
- Correct your display name at any time in the app.
- Delete your account and data from the Account page in the app. Deletion is immediate.
- Withdraw consent by deleting your account.
- Raise a grievance with our Grievance Officer (section 10).
- Nominate another person to exercise these rights for you in case of death or incapacity, by writing to us.
To make any request, email mahmedhussain@outlook.com from the address linked to your account.
8. Age
One Day World is only for people aged 18 or older. We do not knowingly collect information from anyone under 18. If we learn that a user is under 18, we will delete their account.
9. Security
Data is encrypted in transit and stored with Cloudflare. Your sign-in session is kept in your iPhone's secure keychain. Only our server can create messages, apply bans or delete accounts. No method of storage is perfectly secure, but we take reasonable steps to protect your information.
10. Grievance Officer
