Player tools and local exports
Your preferred length unit is saved in this browser when browser storage is available. The stats page reads existing daily saves on this device; it does not create an account, upload your history, or publish a global ranking. Archive replays and friend challenges are kept separate from original daily history.
Score images and CSV history exports are generated locally after you select the export control. Score images contain scores, mode and date, not answers or guesses. Downloading creates a local file; choosing the system Share image action sends that file only through the destination you select. These tools do not change your analytics choice.
Effective date: September 23, 2026. Size It Up Daily is designed to work without an account. We minimize data collection and keep ordinary game progress on your device.
Information stored in your browser
The game uses local browser storage to remember the current UTC daily challenge, completed round scores, saved estimates, daily streak, number of completed dailies, and personal best score. These records do not contain a name, email address, advertising identifier, or precise location. They are not automatically synchronized to a server.
You can remove these records through your browser’s site-data controls. Clearing storage resets local progress and statistics. Private browsing modes may discard the records automatically when the session closes.
Hosting and security logs
Friend challenge links include the five round identifiers and the sender’s total score. Anyone with the link can read those values; individual guesses are not included. Challenge progress and the recipient’s first completed result stay in that browser. Clearing site data or using another browser starts a separate attempt.
The site is hosted on Cloudflare Pages. Like most hosting and security providers, Cloudflare may process technical request information needed to deliver and protect the service. That information can include an IP address, request time, requested URL, browser or device details, response status, and security signals. Cloudflare’s handling of its platform data is governed by its own privacy commitments.
Analytics and advertising
The site offers optional Google Analytics 4 measurement. Google Analytics does not load unless you select Allow analytics. If you allow it, we use aggregate page, referrer, browser, device, coarse location, and interaction information to understand how the site is used. We do not send your name, email address, saved estimates, daily streak, or game progress to Google Analytics.
Your analytics choice is stored in this browser so the site can remember it. You can reopen the choice at any time with Analytics choices in the footer. Declining analytics does not limit the game.
The site uses Adsterra Popunder and Social Bar advertising. Popunder ads may open another browser tab or window after an interaction; Social Bar ads may appear over the page. These advertising scripts load when you visit a page, separately from the optional Google Analytics choice. Google AdSense is not enabled.
Advertising providers may use cookies, web beacons, IP addresses, or other identifiers to deliver and measure ads. Advertiser destinations are operated by third parties and have their own privacy practices. Browser privacy controls can restrict third-party cookies and pop-ups. The Analytics choices control applies to Google Analytics only.
External links
The sources and editorial pages link to public institutions, scientific agencies, standards bodies, manufacturers, landmark operators, and the independent game that inspired current search interest. Following an external link takes you to another organization’s site. Its privacy policy and security practices apply there.
Children’s privacy
The game is a general-audience educational puzzle. It is not directed specifically to children under 13, and it does not ask players to submit age, school, name, or contact details. If the service later introduces accounts, comments, or user submissions, age-appropriate privacy and moderation controls will be assessed before launch.
International access
The static site can be accessed internationally. Browser-local records stay on the device unless the browser itself synchronizes site data under the user’s separate account settings. Hosting request data may be processed across Cloudflare’s global network as required to deliver and secure the site.
Your choices
- Play without creating an account.
- Clear local progress through browser site-data settings.
- Decline optional analytics or change the choice from the site footer.
- Avoid external links or review the destination’s policy before continuing.
Policy changes
Material changes will be reflected in the effective date and in the relevant section. New analytics, advertising, account, comment, upload, or newsletter features would require a specific disclosure rather than being silently covered by broad language.
