Privacy policy
Last updated: March 30, 2026
This Privacy Policy describes how Pokobase (“Pokobase”, the “App”) handles information when you use our mobile application. The App is operated by Thjis, registered in the Netherlands (“Thjis”, “we”, “us”, “our”). By using the App, you agree to this policy together with our Terms of Use.
Summary
Pokobase does not require you to create an account. Your collection progress and preferences are stored on your device so the App can work offline and remember what you mark as caught. We do not operate our own social network or user database inside the App.
If you use the free, ad-supported version, Google Mobile Ads (AdMob) may collect or use device and advertising-related data as described below. If you purchase an ad-free entitlement, we aim not to initialize the ad stack for your use of the App on that basis.
We use RevenueCat to manage in-app purchases. Apple or Google process payments. We do not sell your personal information.
Data controller (EU / UK)
For the purposes of the EU General Data Protection Regulation (“GDPR”) and the UK GDPR / Data Protection Act 2018, the controller is Thjis, registered in the Netherlands. For privacy requests, contact us at the email below. You may lodge a complaint with a supervisory authority, including the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) or, if you are in the UK, the ICO.
Information stored on your device
The App stores collection state, settings, and similar data locally (for example using secure storage APIs on your device). That data remains on your device unless you delete the App or clear app data, unless a platform feature syncs backups under your Apple or Google account according to their policies. We do not receive a copy of your full collection list on our servers solely from normal use of the App.
Google Mobile Ads (AdMob)
When ads are enabled, we use Google’s advertising SDK. Google may process identifiers and usage data to show and measure ads, prevent fraud, and personalize ad experiences depending on your choices and applicable law. Google acts as an independent controller or processor for various processing activities as described in Google’s policies. See: policies.google.com/privacy and Google’s information for partners. You can adjust ad-related settings on your device (for example “Limit Ad Tracking” / personalized ads settings) and, where available, use in-app options such as “Ad privacy” in Pokobase settings.
RevenueCat (purchases SDK)
We use RevenueCat, Inc.’s SDK to manage in-app purchases and entitlements. RevenueCat may process technical identifiers and subscription or purchase-related data on our behalf (for example to validate entitlements with Apple or Google). RevenueCat may act as a processor under the GDPR where applicable. See: revenuecat.com/privacy.
Purchases and payment platforms
Paid products are billed and managed by Apple (App Store) or Google (Google Play), not by us directly. They process payment and account data under their own privacy policies. We do not receive your full payment card details.

- Google: policies.google.com/privacy
Offers, pricing display, and product tests
We may show different purchase offers, prices, or paywall layouts to different users based on factors such as region, language, app store country, device type, or similar segments (for example A/B tests), in line with platform rules and this policy.
Legal bases (EU / UK)
Where the GDPR or UK GDPR applies, we rely on: contract (to provide the App and honour purchases as mediated by stores and RevenueCat), legitimate interests (to secure the App, prevent abuse, and respond to support you request), consent where required for certain advertising or analytics processing governed by Google or the platform (for example where the ATT or GDPR consent frameworks apply), and legal obligation where required.
International transfers
RevenueCat, Google, Apple, and their subprocessors may process data in the United States and other countries. Where required, they use appropriate safeguards (such as Standard Contractual Clauses) as described in their respective policies.
Retention
We do not maintain a central user database for routine App use. Support emails are kept only as long as needed to handle your request and for ordinary business, legal, and tax records. Processors such as RevenueCat, Google, and Apple retain data according to their own policies.
Your rights (EU / UK)
Where applicable, you may have the right to access, rectify, erase, restrict, or object to certain processing, and to data portability. To exercise rights against Thjis, email us at the address below. For ad-related data held by Google, use Google’s tools and device settings. For subscription records, use your Apple or Google account tools.
California residents (CPRA)
This section supplements the above for California residents. We do not sell personal information for money. Advertising through Google may involve “sharing” or “targeted advertising” as defined under California law; Google’s disclosures and your opt-out rights are described in Google’s California privacy notices and your device settings.
Your rights. You may have the right to know, delete, and correct personal information, and to opt out of sale/sharing where applicable. Contact us at the email below. We will not discriminate against you for exercising these rights. You may designate an authorized agent where permitted by law.
Support and communications
If you email us for support, we receive what you send (such as your email address and message content) to respond. We do not use support emails for marketing unless you ask us to.
Legal and safety
We may preserve or disclose information if we believe in good faith it is required by law, legal process, or to protect the rights, safety, or integrity of users or the public.
Children
The App is not directed at children under 13 (or the minimum age required in your country to consent to data processing). If you are not old enough, please do not use the App.
Changes to this policy
We may update this Privacy Policy at our discretion. We will post the revised version on this page and update the “Last updated” date. Unless a shorter period is required by law or by an app store, we will notify users at least one (1) month before material changes take effect (for example via an in-app notice, email if we have your address from support, or another reasonable method). Continued use after the effective date means you accept the updated policy, except where applicable law requires your separate consent.
