Your data

Privacy Policy

Last updated: 3 November 2026 · Effective upon publication

Krawl is made by Friedemann Lipphardt, an independent (solo) game developer based in Japan ("we", "us", "I"). This policy explains what information the Krawl mobile game collects, why, who it's shared with, and the choices you have. It's written to be read, not just filed.

1. Who is responsible for your data

The data controller for Krawl is Friedemann Lipphardt (sole proprietor), Japan. For any privacy question or request, contact support@krawl-game.com.

2. What we collect

Information you give us

• Optional account linking. Krawl works anonymously by default. If you choose to link a Unity Player Account to back up your progress across devices, Unity hosts the sign-in and we receive only an identifier for that link. We never see your password. Linking is required before an in-app purchase, so paid items cannot be stranded on an account you can't recover.
• Names other players can see. You can choose a nickname (the default is "Nameless Delver"). It is shown to other players on the leaderboards, in friend lists (with a number Unity adds, such as name#1234) and on guild rosters, and the nickname of a player who invites a friend to a guild is shown on that invite. If you found a public guild, its name is listed to every player; private (invite-only) guilds are not listed. Filtering: the game checks your nickname against a name filter and then sends it straight to Unity's player-name service; our server filters guild names and the copy of your nickname that is stored on a guild's roster. Guild names can be reported in the game, and so can another member's nickname on a guild roster (a REPORT button on that member's row). When three reporters who are still members of that guild report the same name, it is hidden in that guild for 30 days (a new report renews it), and a guild name taken down after reports comes back after 30 days. Names on the leaderboards, in friend lists and on invites cannot be reported in the game; email us to report one.
• Support correspondence. If you email us, we keep your message and address to reply and to help.

Information collected automatically

• Device & technical data: device model, operating system and version, language and region, app version, and a randomly generated player/install identifier.
• Advertising data: Unity Ads processes device and advertising signals according to your device settings and its privacy policy. On iOS, access to the Apple IDFA requires your permission through App Tracking Transparency. Krawl requests non-personalized ads unless that permission is granted. On Android, Krawl requests non-personalized ads.
• Gameplay & analytics: in-game events such as runs started, floors reached, features used, and crash/diagnostic reports — used to fix bugs and balance the game.
• Purchase records: confirmation that a purchase occurred and which product, provided by Apple or Google. We never receive your credit-card or full payment details — those are handled entirely by the app stores.
• Approximate location: a coarse, country-level location derived from your IP address (we do not collect precise GPS location).

3. The services we use

Krawl relies on a small number of third-party providers to run. When they process data on our behalf, they act as our service providers; some ad partners may also act as independent controllers for advertising. Their own privacy policies govern how they handle data:

• Unity Gaming Services (Unity Technologies) — anonymous authentication, cloud save, cloud code (the scripts that run our guild and daily-shop servers), remote config, analytics, leaderboards, and friends. Unity privacy policy ↗
• Unity Ads — serving in-game advertisements. Unity privacy policy ↗
• Apple App Store and Google Play — app distribution and processing of in-app purchases. Apple ↗ · Google ↗

We do not use any other advertising network, mediation provider, or third-party analytics or attribution SDK.

4. Why we use your data

• To operate the game, save and sync your progress, and process your purchases.
• To show and measure advertising. The Remove Ads purchase disables banners and interstitials; optional rewarded ads remain available.
• To understand how Krawl is played so we can fix bugs, balance difficulty, and improve it.
• To protect the game and players from cheating, fraud, and abuse.
• To respond to your support requests and to meet legal obligations.

Where the EU/UK GDPR applies, we rely on these legal bases: performance of our contract with you (running the game and purchases), our legitimate interests (analytics, security, improvement), your consent (personalized advertising, where required), and compliance with legal obligations.

5. Advertising & your choices

Krawl is free to play and supported by ads. You have real control over them:

• Remove banner and interstitial ads with the one-time "Remove Ads" in-app purchase. Rewarded ads are optional and remain available when you choose to watch one.
• Personalized ads are off unless you turn tracking on. iOS asks once, with the App Tracking Transparency prompt. Unless you explicitly allow it, Krawl tells Unity Ads to serve non-personalized ads — this is the default, and it also applies if you have not answered the prompt yet. You can change your answer at any time under Settings → Privacy & Security → Tracking, or per-app under Settings → Krawl.
• Android: Krawl requests non-personalized ads. Your device's advertising ID controls are available in Android settings; their location depends on the device and Android version.
• Gameplay analytics can be switched off in the game, under Settings → Privacy → Gameplay Analytics. Turning it off stops collection; it does not affect saved progress or purchases.
• Deleting your account (Settings → Account → Delete Account) also requests deletion of the analytics data associated with you.

6. Children

Krawl is not directed to children under 13 (or the equivalent minimum age in your country). We do not knowingly collect personal information from children under that age. If you believe a child has provided us information, contact support@krawl-game.com and we will delete it. Ad personalization controls are described in Section 5.

7. How long we keep data

We keep your saved-game and account-link data for as long as you use Krawl, and until you delete your account or ask us to delete it. We do not have an automatic process that deletes or anonymizes the data of inactive accounts. Analytics and diagnostic data are retained only as long as needed for the purposes above. Purchase records are kept as required for tax, accounting, and fraud-prevention purposes.

8. International transfers

We and our service providers may process your data in countries other than yours, including the United States, where data-protection laws may differ. Where required, our providers use appropriate safeguards (such as the European Commission's Standard Contractual Clauses) for these transfers.

9. Your rights

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal data; to object to or restrict certain processing; and to withdraw consent. To exercise any of these, email support@krawl-game.com and we'll respond within the time required by law.

• EEA/UK: you also have the right to complain to your local data-protection authority.
• California (CCPA/CPRA): you have the right to know, delete, and correct your information, and to opt out of the "sale" or "sharing" of personal information. We do not sell your personal information for money. Sharing advertising identifiers with ad partners for cross-context behavioral advertising may be considered "sharing"; you can opt out using the controls in Section 5 — declining the iOS tracking prompt is itself an opt-out, and it is the default. We do not discriminate against you for exercising your rights.
• Japan (APPI): you may request disclosure, correction, or deletion of your personal data as provided under the Act on the Protection of Personal Information.

Deleting your account and data

In the game: open Settings → Account → Delete Account and confirm. The game then:

1. tries to hand over any guild you lead and to take you out of your guild, and withdraws guild invites you sent. The first attempt is best effort and has a time limit. A guild you lead goes to its earliest-joined member who does not already lead another guild; if no member qualifies, the guild is removed even though it still has members;
2. removes all your Unity Friends relationships (friends, pending requests and blocks);
3. deletes your saved game and the other data Unity Cloud Save holds for you, including the invites you received and sent;
4. removes your scores from the leaderboards;
5. asks Unity Analytics to delete the analytics data associated with you;
6. deletes your Unity Gaming Services player account, the player ID the game signed in with, together with its link to a Unity Player Account if you linked one, on every device that used it. The Unity Player Account itself is held by Unity and is not deleted: manage or delete that with Unity;
7. removes the local copy of your save from the device and starts a new anonymous profile.

When the deletion stops: the game stops, keeps your account, and tells you what went wrong, so you can try again, if: a purchase is still being processed; your save could not finish syncing; your friends could not all be removed; your cloud-save data could not be erased, which includes the case where the server's guild hand-over does not finish; your leaderboard scores could not be removed (a temporary failure); or the account deletion itself fails. Steps that already finished stay done when it stops: you may already have left your guild, or lost your friends list or cloud save, while your account still exists. If the game cannot remove your leaderboard scores because of a configuration problem on our side, deletion still goes ahead and those scores can remain: email support@krawl-game.com and we will remove them.

What is kept:

• The leaderboards reset on a schedule (weekly and every four weeks). A reset clears the board and no copy of the old scores is kept. While a score is on a board, the board shows your nickname beside it.
• The purchase records Apple and Google keep, and data held by Unity Ads and by Unity's engine diagnostics, which the game has no way to delete (see Unity's privacy policy).
• Our moderation log (private, server only) keeps the reports that were filed, with the player IDs of the reporter and the reported player and the reported name. It has no time limit: reports leave it only when the log is full (1,000 rows): then the oldest rows of any reporter who has more than 5 go first, and after that the oldest rows. Reports you filed, about guild names or about nicknames, stay in it. Deleting your account does not remove them: they are a moderation record.
• A report about your nickname in a guild also stays on that guild's record, until the guild's next update after 30 days from the latest report (and for as long as the guild exists). It applies only to that player ID and name while you are on the guild; deleting your account does not bring a hidden name back, because a new account has a new player ID.
• If you reported a nickname in a guild, your player ID stays in that report on the guild's record for the same time, including guilds you have since left. A report you filed about a guild name leaves the guild's record after about 30 to 60 days, at the guild's next update.
• Guild invite records (your player ID as the sender of an invite, for about a day) and removal markers (your player ID if you were removed from a guild, 7 days) stay on that guild's record until its next update.
• Invite send-limit records (timestamps only, up to 10 per player) stay stored; they stop counting after a day.
• A guild you founded keeps your player ID inside the guild's own ID after you hand it over (it is visible in the guild directory and in invite codes).
• Our scripts write your player ID to our server log only when your leaderboard scores could not be removed during deletion, so that we can remove them by hand. Unity's own service logs may also record which player made a call.

Without the game: email support@krawl-game.com to request deletion of your account and data. Tell us your name with its number (shown on the Friends tab, for example name#1234) or your Player ID (shown under Settings → Account, with a Copy button), so we can find your records.

10. Security

We use reasonable technical and organizational measures to protect your data. No method of transmission or storage is perfectly secure, but we work to keep your information safe and to limit what we collect in the first place.

11. Changes to this policy

We may update this policy as Krawl evolves. When we make material changes, we'll update the "last updated" date above and, where appropriate, notify you in-game. Continuing to play after changes take effect means you accept the updated policy.
