Last updated and effective: July 16, 2026 · Chase It! for iPhone, iPad, and Android
This policy explains who we are, what Chase It! (“the app”) stores, what Google collects through the advertising and analytics software we embed, and the choices and rights you have.
Chase It! is made and published by Ho Van Hai, an independent developer in Vietnam, trading as Soucean. Under the GDPR and equivalent laws, that individual is the data controller for this app.
We are a one-person operation and are not required to appoint a Data Protection Officer, so we have not appointed one. Privacy mail goes directly to the developer at the address at the bottom of this page.
Chase It! has no accounts, no sign-in, and no text fields — there is nowhere in the app to type personal information, and we never ask for any. The app saves your setup locally, using your device’s standard app-preferences storage, so it survives closing the app. This never leaves your device and we cannot see it:
soundOn)speed_fish, size_fish, and the same for the mouse and the roach), plus older global values kept so upgrades don’t lose your setup (speedMultiplier, sizeMultiplier)bg_fish and so on) and which prey the home screen last showed (stageSpecies)disabledVariants)variantUnlocks)updatePromptedVersion)Deleting the app erases all of it. Because there is no account, these settings cannot be recovered or moved to another device.
The app embeds software from Google. When the app runs, these services collect data directly from your device to Google, under Google’s own privacy policy. We see only aggregated reports; we never receive a copy of the raw data, and there is no other company involved.
| Service | What it collects | Why |
|---|---|---|
| Google AdMob | Your advertising identifier — IDFA on iPhone and iPad, but only if you allow tracking; Advertising ID on Android — plus IP address, device model and settings, and how the banner, interstitial, and rewarded ads are interacted with. Apple’s SKAdNetwork and Android’s Privacy Sandbox also measure ad performance without identifying you. | To show ads and measure them. Ads are what keep the game free. |
| Firebase Analytics | Six in-app events, and nothing else: screen_view, play_species, settings_open, game_exit (which prey, and how many catches), unlock_prompt, unlock_success. Google attaches your device model, OS version, an approximate region derived from your IP address, and a randomly generated app instance identifier. On Android it also receives the Google Play install referrer. |
To see which prey and settings actually get used |
| Firebase Crashlytics | Crash reports: what the app was doing when it stopped, device model, OS version, and a random Crashlytics installation identifier. Release builds only — crashes in our own test builds stay on our machines. | To find and fix crashes |
| Firebase Remote Config | Reads settings from Google’s servers, not from any server of ours. It is a one-way read: it sends the same random app instance identifier and nothing about how the app is used. | To adjust the game and flag broken versions without shipping an update |
None of these events contain your name, email, or anything you typed — the app never asks for those. We do not set a user ID and we record no user properties, so nothing Google receives through these events is tied to you as a person. Google’s practices are described in the Google Privacy Policy and, for ads specifically, in how Google uses data in AdMob.
On startup the app asks Firebase Remote Config for the minimum and latest published version numbers and compares them with the version installed on your device. If your copy is too old we show a notice, and it may offer to open your app store. Your version number is compared on your device — it is not reported to us.
For anyone in the European Economic Area or the United Kingdom, the GDPR requires us to name a legal basis for each purpose. Ours are:
| What | Purpose | Legal basis |
|---|---|---|
| Settings on your device | Remember your setup | Not processed by us at all — they never leave your device |
| Personalized ads and the advertising identifier | Fund a free game | Your consent — Art. 6(1)(a) |
| Analytics events | See what is actually used | Your consent — Art. 6(1)(a) |
| Non-personalized ads | Fund a free game when you decline consent | Legitimate interests — Art. 6(1)(f) |
| Crash reports | Keep the app from breaking | Legitimate interests — Art. 6(1)(f) |
| Remote Config and version check | Ship fixes, flag broken versions | Legitimate interests — Art. 6(1)(f) |
Where we rely on legitimate interests, we have weighed them against your privacy: all of it is limited to keeping a free game working and none of it identifies you personally. You can object at any time — see Your rights.
Shortly after you first open the app on an iPhone or iPad, it shows Apple’s tracking prompt and asks permission to use your device’s advertising identifier (IDFA) for personalized ads. We ask once; iOS only allows the prompt a single time.
If you say no, you will still see ads — they will just be non-personalized. Saying no does not lock, limit, or slow down any part of the game, and your cat will not notice the difference.
You can change your mind at any time:
Before any personalized ad is requested and before analytics collection begins, the app shows a consent form provided by Google’s User Messaging Platform, and asks whether you agree. Nothing personalized runs until you answer. You can reopen that form from the app’s settings and change or withdraw your answer at any time; withdrawing is as easy as giving consent, and costs you nothing in the game.
You also have the right to lodge a complaint with your national data protection authority. A directory of EEA authorities is published by the European Data Protection Board; in the UK, the authority is the Information Commissioner’s Office. You are welcome to contact us first, but you are not obliged to.
We want to be blunt about this rather than hide behind wording. When you allow tracking, your advertising identifier goes to Google so it can personalize the ads you see. Under the CCPA as amended by the CPRA, that counts as “sharing” for cross-context behavioral advertising, and you have the right to opt out of it.
Depending on where you live, you have some or all of the following rights over your personal data: to access it, to have it corrected or erased, to restrict or object to how it is used, to receive it in a portable form, and to withdraw consent you previously gave.
Here is the honest, practical answer about exercising them with us. We hold no account, no email address, and no identifiable records — so if you write to ask what we have about you, the answer will almost always be that we have nothing to look up, because there is no key to look you up by. That is by design, not evasion.
The data that does exist is held by Google, and Google is the only party that can act on it. Use the Google Privacy Policy for that. Resetting or deleting your advertising identifier, as described above, severs the link between your device and past ad activity. Deleting the app erases everything held locally.
If you do write to us, we will reply within 30 days.
We are based in Vietnam, and Google operates a global infrastructure, so data collected through the app is processed on Google servers outside your country — including in the United States. We do not transfer anything ourselves, because nothing is ever sent to us. For transfers out of the EEA and the UK, Google relies on the European Commission’s Standard Contractual Clauses and the frameworks described in its own privacy policy.
We are a Vietnamese controller, so Decree No. 13/2023/ND-CP on Personal Data Protection applies to us. The rights it grants you — to know, to give and withdraw consent, to access, to correct, to delete, to restrict and object, and to complain — are covered by the sections above, and the same contact address applies.
Chase It! is built for cats to play and for their owners to set up. It is intended for a general audience, it is not directed to children under 13, it is not published in a children’s category, and we do not knowingly collect personal information from children under 13. If you believe a child has provided such information, contact us and we will act on it.
The strongest security measure we have is structural: we do not operate a server, hold no accounts, and store no personal data. There is no database of ours to breach. Everything the app sends travels over encrypted connections to Google, whose security is described in their privacy policy. Data on your device is protected by your device’s own operating system and passcode.
We do not operate a server that stores your data, so we retain nothing. Your settings live on your device for as long as the app is installed and are erased when you delete it. Data collected by Google is retained under Google’s own schedules, described in their privacy policy.
If this policy changes we will update this page and the date at the top. Meaningful changes will be noted in the app’s release notes. Where a change requires your consent under applicable law, we will ask for it before the change takes effect.
