Privacy Policy

Last updated: August 18, 2026

This Privacy Policy describes how Daily Skyline ("we," "us," or "the App") handles information when you use the Daily Skyline mobile application and related services, including this website (dailyskyline.muratoncu.com).

Daily Skyline is a daily logic puzzle game. We designed it so you can play without creating an account. We do not sell your personal data. We do not use advertising or tracking SDKs, and we do not track you as Apple defines tracking (linking data from the App with third-party data for advertising, or sharing data with a data broker).

1. Who we are

Daily Skyline is operated by Murat Hüdavendigar Öncü. Learn more on our About page. Contact for privacy questions: dailyskyline@muratoncu.com.

2. Information we collect

Depending on how you use the App and website, we may process:

Progress stored on your device

Puzzle progress, streaks, stats, difficulty preferences, and similar gameplay data are stored locally on your device (for example in on-device storage). This data is not transmitted to our servers as part of normal play. We do not require an account for this. If you delete the App or clear its data, this local progress may be lost unless you use a platform feature that preserves it (for example, a device backup).

Anonymous global solve stats (Supabase)

When you complete a puzzle, the App sends a limited, anonymous gameplay record to our backend hosted on Supabase (via an RPC such as "record_anonymous_solve") so we can show community features like how many players solved today or percentile-style comparisons. This is part of the App's core functionality — there is no separate opt-in toggle.

That record may include:

It does not include your name, email, Apple ID, Game Center player ID, account ID, advertising identifier, or hardware serial. We do not use these stats to identify you, advertise to you, or combine them with third-party data for advertising. The public "players solved today" counter only counts daily puzzle completions; archive replays may be stored for aggregate analytics but do not inflate that counter.

Skyline Points ranking (anonymous install token)

To show how your Skyline Points rating compares to other players (a "Top %" style ranking), the App stores a random install token on your device and sends it with your latest rating to Supabase. The token is a UUID we generate — not your Apple ID, Game Center ID, advertising identifier, or hardware ID. We use it only so one install has one rating in the pool (instead of counting the same device many times). Uninstalling the App or clearing its data generates a new token.

Game Center (optional)

If you choose to use Apple Game Center for leaderboards or achievements, related data is handled by Apple's GameKit under Apple's privacy policy and your Game Center settings. Daily Skyline does not store or transmit your Game Center identity, player ID, or profile to our own servers. You can leave Game Center or limit sharing in iOS Settings.

Local reminders (optional)

If you enable reminders, the App schedules local notifications on your device only. That can include a daily puzzle reminder (the hour can follow when you usually play, unless you set it yourself) and a later last-call reminder if today is still unsolved, your streak is alive, and you have no Streak Freeze left. We do not register a push token with our servers, and reminder scheduling does not send notification content to us. You can turn reminders off anytime in system or in-app settings.

Anonymous app signals (Supabase)

To understand whether optional features are working, without identifying you, the App may send small anonymous signals to our Supabase backend. This is part of the App's core functionality. There is no separate opt-in toggle.

Each signal is just a type, a date, and a platform (for example iOS). Never a push token, your Game Center identity, the content of a notification, or whether you actually left a review (Apple does not expose that to developers). These signals are not linked to your Apple ID, advertising identifier, or Game Center profile, and we do not use them for advertising.

Website waitlist

The public site now links to the live App Store listing. If you previously joined the launch waitlist, we still hold the email address you submitted so we can send related product updates. We store it with our hosting database provider (Supabase) for that purpose only. We do not sell waitlist emails or use them for unrelated marketing. You can ask us to remove your address anytime by emailing dailyskyline@muratoncu.com.

Feedback you send us

If you email us or submit optional in-app feedback, we receive the content you provide (and standard email metadata such as your address). We use this only to respond and improve the App.

Website visits

Our website host may collect standard server logs (for example, IP address, browser type, and pages requested) for security and reliability. We do not run advertising trackers on this site.

3. How we use information

4. What we do not do

5. Sharing

We share information only when needed to provide the service:

6. Retention

Local progress stays on your device until you clear it or remove the App. Anonymous aggregate stats, Skyline Points ratings, and app signals on Supabase are retained only as long as useful for those community and product features. Waitlist emails are kept until you ask us to remove them or until we no longer need them for launch communication. Support emails are kept as long as needed to handle your request and for reasonable business records.

7. Children

Daily Skyline is a general-audience puzzle game. We do not knowingly collect personal information from children for accounts or marketing. If you believe a child has provided personal information through support channels, contact us and we will delete it.

8. Your choices

9. Future features

We may later add optional accounts, cloud sync, Pro / in-app purchases, Android builds, or additional analytics needed to run the product safely. Account and cloud-sync features are not active in the current App release. If we enable them or change data practices, we will update this Privacy Policy and, where required, ask for fresh consent or explain new choices in the App.

10. International users

The App and website may be operated from servers in different regions (including infrastructure provided by Supabase and our website host). By using the service, you understand that information may be processed where we or our providers operate, with appropriate safeguards.

11. Changes

We may update this policy from time to time. The "Last updated" date at the top will change when we do. Continued use after an update means you accept the revised policy, except where applicable law requires otherwise.
