Effective November 2, 2026. This policy describes the supplied static version of PurrTools.
Information handled by this site
Tool inputs are processed in your browser and are not sent to an application server. PurrTools has no user accounts or external fonts. Our calculators do not send their input values to an application server. Google AdSense is a separate third-party advertising service; its script can process browser or device information and use cookies as described below.
Local storage
The weight tracker stores dates and weights under purrtools.weights.v1 in your browser’s localStorage. It stays until you delete it or clear site data. Anyone with access to the same browser profile may see it. Private browsing or browser restrictions can prevent persistence. There is no cloud backup.
Your controls
Delete individual rows, clear the diary, or export a CSV from the weight tracker. Exported files remain on your device until you delete them separately. Other calculator values are not intentionally saved by this site, though your browser may remember form values.
Hosting and external links
A hosting provider may process standard request data such as IP address and requested URL. Its policies apply. Following an external reference takes you to a different site with its own privacy practices. Site owners must update this policy if they add services or change data handling.

Google advertising
PurrTools includes the Google AdSense script for publisher ca-pub-3599688410324159. Loading this service may send request information to Google even if no advertisement is displayed. Processing depends on the service, region and consent configuration.
Third-party vendors, including Google, may use cookies to serve ads based on previous visits to this or other websites. Google and its partners may use advertising cookies to personalize ads based on those visits. Ad delivery may also involve web beacons, IP addresses, and device or browser information for delivery, measurement and abuse prevention.
You can manage Google ad personalization in My Ad Center and explore participating vendors’ choices at YourAdChoices. Turning off personalization does not necessarily stop ads, all processing, or all cookies. See how Google uses information from partner sites.
Consent and withdrawal
Consent messages, vendor details and withdrawal options must be supplied by the configured certified consent-management service where required. This local preview does not yet have a published consent message. A generic cookie notice is not a certified consent platform. Browser settings can clear site data, but this also removes the local weight diary.
The operator must keep this policy and the consent-message vendor details aligned with the live configuration. See our Advertising disclosure.
Contact by email
If you email hutaodewang@gmail.com, your address and the message you choose to provide are handled by the email service and used by the site operator to respond. Avoid sending sensitive information. You may request handling or deletion of correspondence at the same address; actual retention is subject to the email service and applicable obligations.
