Privacy Policy
Last updated 20 September 2026
Daily Block is a puzzle game made by one person. It does not ask for your name, your email or your location, and it never sells your data. This page lists exactly what it does collect and why.
This policy covers the Daily Block iPhone app and the website at dailyblock.app. Both are operated by Sundar Singh (“I”, “me”). Contact: sundarsingh19@gmail.com.
1. Your account
On first launch the app creates an anonymous account for you automatically. There is no sign-up, and it is not tied to your identity — it is a random identifier plus a generated display name such as Blocker-4821, which you can change. A two-letter country code is recorded once, taken from your device’s language and region setting, not from your IP address or GPS.
Signing in with Apple or Google is optional. Its only purpose is to move your streak and scores to a new phone. If you do, that provider tells me an account identifier and, depending on your choice at the prompt, an email address — with Sign in with Apple you can have Apple relay a private address instead, and that works fine here. I never receive your password.
2. What the app stores
| Data | Why |
|---|---|
| Daily results: the date, your score, how many moves you made, and a hash of your move sequence | To score the puzzle on the server rather than trusting the app, and to place you in the day’s percentile |
| Streak data: current and longest streak, freezes held, the last date you played | The streak is the point of the game |
| Display name and country code | Leaderboards |
| Your invite code and the accounts you have added as friends | The friends leaderboard. Adding a friend requires their code — nothing is read from your contacts |
| Purchase and subscription status | To unlock what you paid for and keep it across devices |
Your score is calculated by replaying your moves on the server. If that replay disagrees with the app, the result is flagged and left out of the leaderboard.
3. Analytics and crash reports
The app records a short, fixed list of product events — app opened, daily started, daily finished, share tapped, endless run ended, an ad shown, the paywall viewed, a purchase made, a streak milestone reached. Each event carries your account identifier and your device model, iOS version and manufacturer, so I can tell a bad update from an old phone.
Crash reports are collected when the app fails, and include the stack trace and device details. They are configured not to attach personally identifying information.
Neither of these reads your photos, contacts, messages, location or anything you do in other apps.
4. Advertising
Endless mode shows ads from Google AdMob. The daily puzzle never does. To serve and measure them, Google receives device and usage information including your IP address, a device identifier and your interaction with the ad.
On iOS, the identifier used for cross-app tracking (the IDFA) is only available if you allow it when iOS asks. Decline and the game works exactly the same — you simply get less relevant ads. You can change your mind at any time in Settings → Privacy & Security → Tracking. Buying Remove Ads or subscribing to Block Club removes ads altogether.
5. Who processes data for me
I run no servers of my own. These companies process data on my behalf:
| Service | What it handles |
|---|---|
| Supabase | Accounts, scores, streaks, friends — the game database |
| Google AdMob | Ads in Endless mode |
| PostHog | Product analytics |
| Sentry | Crash reports |
| RevenueCat | Purchase and subscription status |
| Apple | App distribution, payments, optional sign-in |
Each publishes its own privacy terms. Payments are handled entirely by Apple — I never see your card details, billing address or Apple ID password.
6. What is never collected
- Your precise or approximate location
- Your contacts, photos, camera, microphone or health data
- Your real name, postal address or phone number
- Payment card details
Your data is not sold, and is not shared for anyone else’s advertising.
7. Notifications
The app can send one reminder at about 8pm, on days you have not played. It is scheduled on your device by iOS — there is no push server and nothing leaves your phone to produce it. Turn it off in the app’s Settings or in iOS Settings.
8. Your rights and how to use them
Depending on where you live — the UK and EEA under the GDPR, California under the CCPA, India under the DPDP Act, among others — you have the right to ask for a copy of your data, to have it corrected, or to have it deleted.
To delete your account and everything attached to it, open Settings → Account → Delete account in the app. It takes effect immediately and removes your profile, scores, streaks, friendships and leaderboard entries. It cannot be undone. If you would rather I did it, email sundarsingh19@gmail.com and I will action it within 30 days.
Deleting your account does not cancel a Block Club subscription — only the App Store can, under Settings → your name → Subscriptions. Purchases stay attached to your Apple ID, so Restore purchases brings them back on a new account.
Where the GDPR applies, the lawful bases are: contract for the account and gameplay data without which the game cannot function; legitimate interests for crash reports, anti-cheat and basic product analytics; and consent for personalised advertising, which is what the iOS tracking prompt asks for.
9. How long it is kept
Account, score and streak data is kept while your account exists. Analytics and crash data are kept for a rolling period by the services above — typically no more than 12 months — after which they are aggregated or discarded.
10. Children
Daily Block is not directed at children under 13, and I do not knowingly collect data from them. If you believe a child has created an account, email me and I will remove it.
11. International transfers
The services above operate globally, so your data may be processed outside your country, including in the United States and the European Union, under the transfer safeguards each provider maintains.
12. This website
dailyblock.app is a set of static pages. It sets no cookies, runs no analytics and embeds no trackers or third-party fonts — the typefaces are served from this domain. The host, Cloudflare, keeps standard server logs for security and abuse prevention.
13. Changes
If this policy changes, the date at the top changes with it, and anything significant will be announced in the app before it takes effect.
