Privacy Policy
Last updated: September 29, 2026.
Overview
This policy explains how the MewMallow website and browser game may store or process information. The project aims to keep data collection limited to what is needed to operate the game, validate optional purchases, understand site performance, and support advertising where enabled.
Local game data
Normal game progress is stored locally in your browser using technologies such as LocalStorage. This can include game progress, owned cats, custom cat names, friendship progress, selected furniture, cosmetic choices, quest state, and settings. This data normally remains in the browser unless a feature specifically requires server-side validation.
Premium purchases
Premium payments are processed through Stripe. The game does not store full payment-card details. To validate a premium purchase, the payment service may store transaction identifiers, bundle entitlement status, a browser installation identifier, timestamps, and purchase-related information supplied by the payment processor. A restore code may be generated so that the same premium entitlement can be connected in another browser.
Advertising and cookies
This site may use Google AdSense or related Google advertising services. Third-party vendors, including Google, may use cookies or similar technologies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables Google and its partners to serve ads based on visits to this site and/or other sites on the Internet.
Users can manage personalized advertising through Google's Ads Settings. Where required by law, an appropriate consent mechanism may be shown before advertising cookies or similar identifiers are used.
Other third-party advertising partners
If additional advertising providers are introduced in the future, this policy will be updated to identify the relevant provider and explain the technologies it uses. Third-party advertising providers may use cookies, web beacons, IP addresses, or other identifiers as permitted by applicable law and platform policy.
Analytics
The site may use privacy-conscious traffic measurement or analytics to understand basic information such as page visits, device categories, and navigation patterns. If Google Analytics or another analytics service is introduced, this policy will be updated as needed.
Children and personalized advertising
MewMallow has a cute visual style but is not designed to use known child-status information for personalized advertising. Advertising configuration must follow applicable Google publisher policies, including restrictions on personalized advertising for users known to be under 13 and for content specifically directed to children.
External services
The website may link to itch.io for game distribution and Stripe-hosted pages for payment processing. Those services operate under their own privacy policies and terms.
Changes to this policy
This policy may be updated when game features, payment systems, analytics, or advertising providers change. The updated date at the top of the page will be revised when material changes are made.
