Privacy Policy

Pawculator — Last updated: September 4, 2026

Pawculator is a calculator with animated cat and dog themes, published under the developer name Cleoworks. This policy explains how the app, support enquiries and these legal pages process personal data.

1. Controller and contact

Cleoworks

Germany

Massoud Salim is the sole proprietor and controller for the processing described as ours in this policy. Cleoworks is the developer name, not a separate legal entity.

2. Calculator and device storage

Calculations run on your device. Calculator expressions are not sent to us. The app has no account registration and we do not operate a calculator, purchase-validation or analytics backend. There is no separate analytics or crash-reporting service integrated by us; advertising diagnostics are described below.

The app stores your selected theme and a cached Premium entitlement in Android app storage. Google's consent tools also store privacy choices. This storage supports the features and settings you request. To the extent personal data is involved, the basis is Article 6(1)(b) GDPR for providing requested app features. Storage or access strictly necessary for those features is covered by Section 25(2)(2) TDDDG; other storage or access requiring consent is based on Section 25(1) TDDDG.

Android backup is enabled. Depending on your device, backup provider and settings, app preferences may be copied to a cloud backup or transferred to another device and restored after reinstallation. We do not operate or receive these backups. Use your Android or backup-provider settings to manage or delete them. Clearing app data or uninstalling removes the local app data but does not necessarily delete an existing backup or records held by Google Play.

3. Advertising and privacy choices

The free version displays a Google AdMob banner. There are no interstitial, rewarded or app-open ads. Premium removes banner advertising. Google's Mobile Ads SDK can collect and share IP addresses (including location inferred from them), device and advertising identifiers, app and ad interactions, and diagnostic information for advertising, measurement, fraud prevention and security. The SDK encrypts transmitted data using TLS.

For users in the EEA and Switzerland, Google's privacy policy identifies Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, as the controller for processing covered by that policy. Google and its service providers process advertising and related data under the applicable Google terms and privacy notices. See Google's Privacy Policy and Google's information for users of partner apps.

Pawculator uses Google's User Messaging Platform (UMP) to collect advertising privacy choices where required. The available choices and providers are shown in the consent message. You can reopen the available choices through Premium → Privacy options. Where processing relies on consent, you can withdraw it there; withdrawal does not affect the lawfulness of processing before withdrawal. The calculator remains usable if you decline optional advertising processing.

Consent-based advertising and measurement use Article 6(1)(a) GDPR and, where applicable, Section 25(1) TDDDG. A non-personalised ad is not automatically exempt from consent requirements. Any ads served after a refusal depend on the processing permitted by your choices, applicable law and Google's configured ad mode. Google's notices and consent message describe its own purposes and any legitimate interests relied upon. Declining consent does not necessarily prevent all technically necessary network traffic.

You can also manage your advertising identifier in Android settings. Resetting or deleting an advertising identifier is separate from changing your consent choices in the app.

4. Premium purchases

Pawculator offers a one-time Premium purchase through Google Play Billing. Google processes payment and transaction information; we do not receive your full payment-card details. The app receives purchase status, a product identifier, a purchase token and acknowledgement information to unlock, check and restore Premium on your Google Play account. It stores a cached entitlement locally and communicates with Google Play for purchase processing and acknowledgement. We do not run a separate purchase server.

Processing necessary to provide the purchase and restore access is based on Article 6(1)(b) GDPR. Any records we are legally required to retain are processed under Article 6(1)(c) GDPR. Google handles its payment and account records under its own terms and retention obligations. See the Google Play Terms of Service and Google's Privacy Policy.

5. Support enquiries

If you email us, we process your email address, message and any information you choose to include to respond and resolve the enquiry. Our email provider processes the message to deliver and store it. Please send only information needed for your request.

The basis is Article 6(1)(b) GDPR for enquiries about a purchase or requested service, or Article 6(1)(f) GDPR for other enquiries, reflecting our legitimate interest in responding to correspondence. We retain correspondence while necessary to resolve the matter, and longer only where required by a statutory retention duty or necessary to establish, exercise or defend legal claims. Such retained records are restricted to those purposes and deleted when those grounds no longer apply.

6. These legal pages

The public legal pages are hosted using GitHub Pages. When you visit, GitHub processes technical request data such as your IP address and browser information to deliver and secure the pages. We add no advertising, analytics scripts, external fonts or tracking cookies to these pages. Following an external link opens the destination provider's service under its own privacy practices.

Our use of hosting is based on Article 6(1)(f) GDPR: our legitimate interest in providing reliable, secure and publicly accessible legal information. GitHub's processing, retention and international transfer arrangements are described in the GitHub General Privacy Statement.

7. Recipients and international transfers

Recipients include Google for advertising, consent and Google Play services; the backup provider selected on your device if backup is enabled; our email provider for support correspondence; and GitHub when you visit these legal pages. Authorities or professional advisers may receive information where a legal duty or the handling of legal claims requires it.

Google and GitHub may process data outside the EEA, including in the United States. Their published transfer arrangements include adequacy decisions, such as the EU–US Data Privacy Framework for covered transfers to certified organisations, and the European Commission's Standard Contractual Clauses where applicable. These mechanisms depend on the recipient and transfer involved; they do not mean that all processing stays in the EU. Details and information about obtaining safeguards are available in Google's transfer framework information and GitHub's Privacy Statement.

8. Retention and deletion

Local settings and the Premium cache remain until cleared or uninstalled, subject to the Android backup behaviour described above. Purchases may be restored from Google Play even after local data is deleted. Advertising and consent data processed by Google follow its retention rules and your settings; see How Google retains data. GitHub and your backup provider apply their own retention rules to data they process. Support correspondence follows the criteria in section 5.

To clear local app data, open Android Settings → Apps → Pawculator → Storage and clear the app's storage; menu names vary by device. This resets the selected theme and cached entitlement. It does not cancel or refund a Google Play purchase, delete Google's records, or necessarily delete backups. No Pawculator account exists to delete. Contact us for requests about information we hold, and use Google's privacy controls for data it controls. You may also contact us for help identifying the appropriate recipient.

9. Your privacy rights

Our processing in the context of our business established in Germany is subject to the GDPR, including when the affected person is outside the EEA. Where the conditions for the respective right are met, you can request access, rectification, erasure, restriction of processing and data portability. You may object to processing based on legitimate interests on grounds relating to your particular situation, and may object at any time to processing for direct marketing. You may withdraw consent at any time without affecting earlier lawful processing. Contact the controller above to exercise your rights; we may need proportionate information to verify the request. Additional rights under applicable local law remain unaffected.

You may lodge a complaint with a data protection supervisory authority, especially in the EEA country where you live, work or believe an infringement occurred. Our local authority is Der Landesbeauftragte für den Datenschutz Niedersachsen, Germany.

You do not need to provide account details to use the calculator. Purchase information is needed to supply Premium, and contact information is needed to answer an enquiry. We do not use your data to make solely automated decisions producing legal or similarly significant effects under Article 22 GDPR. Google's advertising may involve profiling to select ads, as described in its notices and your consent choices.

10. Children and young users

Pawculator is intended for a general audience aged 13 and older and is not directed to children under 13. This description does not override local rules on consent by minors. Where Article 8 GDPR applies, a young user's own consent is sufficient only from the age set by the relevant country; in Germany that age is 16. Below that age, consent-dependent processing requires authorisation by a parent or guardian. Contact us if you have a concern about a child's data.

11. Changes

We update this policy when features, providers or processing change and show the revision date at the top. If a change requires new information or consent, we will provide it as required before the new processing takes place.
