Privacy Policy

Last updated 2026-11-10. Your collection is stored on your device by default. Optional accounts, analytics, and advertising are described below.

Your collection data

The Sprite Checklist works without an account. The Sprites you mark as collected or mastered are saved in your browser's local storage on your own device by default. Optional Cloud Sync and certain exports send collection data to our server as described below. Clearing your browser data or using a different device will reset your local progress unless you use Cloud Sync or carry it over yourself with a share link or backup code.

Share links and backup codes

Share links and backup codes encode only which Sprites are checked off, in an anonymous, compressed form. They contain no personal information. Anyone you send a link to can view that collection; only share it if you are comfortable with that.

Membership accounts (optional)

PNG rendering and ZIP packaging happen on your device. Sharing cards check membership without sending your collection. Full checklist PNGs use the same server-generated PDF as printable downloads: your selected season, collected and mastered IDs are sent to generate the checklist, then its pages are converted to images in your browser. These exports and progress are not stored on our server.

When you request a progress PDF, your current checklist is sent to our server to generate the download. We do not keep a separate copy of your PDF or its export progress.

Cloud Sync is optional. You can sign in with Google and unlock membership with a one-time $9.99 purchase. Signing in creates an account and session even before purchase; synced collection data is stored when you use Cloud Sync.

Account data may include your Google account identifier, name, email address and profile image, authentication and session information, your synced Sprite collection, purchase records, and the country your network reports (a two-letter code), which we use for aggregate statistics. Session information may include your IP address and browser user agent. We never receive or store your Google password. Payments are handled by PayPal (if you pay with PayPal) or by our merchant-of-record card payment provider; we never receive or store your card details or PayPal login. For PayPal payments we keep only the PayPal transaction ID, amount and status.

You can download or delete your account and all associated data at any time from your account page — deletion is immediate and removes your collection, sign-in records and purchase record.

Analytics

We use a privacy-friendly, self-hosted analytics tool (Plausible) to understand aggregate traffic — for example, how many people visit a page. It does not use cookies, does not track you across other sites, and does not collect personal data. We may record anonymous events such as a PWA install, with no personal identifiers. We also use Google Analytics to understand site traffic; Google may process device and usage information in accordance with its privacy policy.

Advertising

We may show ads served by Google AdSense to keep the site free. Google, as a third-party vendor, uses cookies to serve ads on this site. Third-party vendors, including Google, use cookies, web beacons, and similar technologies (which may collect your IP address and other identifiers) to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. Where required (for example in the EEA, UK, or Switzerland), we will ask for your consent before advertising cookies are used, and you can change your choice at any time.

Mediavine Programmatic Advertising (Ver 1.1)

The Website works with Mediavine to manage third-party interest-based advertising appearing on the Website. Mediavine serves content and advertisements when you visit the Website, which may use first and third-party cookies. A cookie is a small text file which is sent to your computer or mobile device (referred to in this policy as a “device”) by the web server so that a website can remember some information about your browsing activity on the Website.

First party cookies are created by the website that you are visiting. A third-party cookie is frequently used in behavioral advertising and analytics and is created by a domain other than the website you are visiting. Third-party cookies, tags, pixels, beacons and other similar technologies (collectively, “Tags”) may be placed on the Website to monitor interaction with advertising content and to target and optimize advertising. Each internet browser has functionality so that you can block both first and third-party cookies and clear your browser’s cache. The "help" feature of the menu bar on most browsers will tell you how to stop accepting new cookies, how to receive notification of new cookies, how to disable existing cookies and how to clear your browser’s cache. For more information about cookies and how to disable them, you can consult the information at All About Cookies.

Without cookies you may not be able to take full advantage of the Website content and features. Please note that rejecting cookies does not mean that you will no longer see ads when you visit our Site. In the event you opt-out, you will still see non-personalized advertisements on the Website.

The Website collects the following data using a cookie when serving personalized ads:

  • IP Address
  • Operating System type
  • Operating System version
  • Device Type
  • Language of the website
  • Web browser type
  • Email (in hashed form)

Mediavine Partners (companies listed below with whom Mediavine shares data) may also use this data to link to other end user information the partner has independently collected to deliver targeted advertisements. Mediavine Partners may also separately collect data about end users from other sources, such as advertising IDs or pixels, and link that data to data collected from Mediavine publishers in order to provide interest-based advertising across your online experience, including devices, browsers and apps. This data includes usage data, cookie information, device information, information about interactions between users and advertisements and websites, geolocation data, traffic data, and information about a visitor’s referral source to a particular website. Mediavine Partners may also create unique IDs to create audience segments, which are used to provide targeted advertising.

If you would like more information about this practice and to know your choices to opt-in or opt-out of this data collection, please visit National Advertising Initiative opt out page. You may also visit Digital Advertising Alliance website and Network Advertising Initiative website to learn more information about interest-based advertising. You may download the AppChoices app at Digital Advertising Alliance’s AppChoices app to opt out in connection with mobile apps, or use the platform controls on your mobile device to opt out.

Third-party content

Pages may embed a YouTube video and load web fonts from Google Fonts. When you play an embedded video, YouTube may set its own cookies under its privacy policy. Apart from the advertising described above, we do not sell any data.

Children

This tool is not directed at children under 13. The checklist itself needs no sign-up; analytics and advertising are described above. The optional Cloud Sync features — signing in and the one-time purchase — are only for users aged 13 or older; if you are under 18 you must have a parent's or guardian's permission, including for any purchase. We do not knowingly collect personal information from children under 13, and we do not permit interest-based advertising to be targeted at children. If you believe a child has provided us personal information or made a purchase without permission, contact us and we will delete the data and refund the purchase where appropriate.
