Current behavior
Paper Size Lab does not activate advertising, personalization, or marketing cookies. Google Analytics loads only after you choose Allow Google Analytics. Paper conversions are calculated in your browser and are not attached to a user account. If you choose Save in a production tool, its non-file settings and notes are stored in local browser storage so you can restore them on that device. This storage is not used for advertising and can be deleted from the tool or browser settings.
Anonymous first-party measurement
The site uses session storage for a random, per-session analytics identifier and local storage for a simple visited-before flag. The flag is not unique and no persistent visitor ID is sent. These values support privacy-conscious traffic and feature measurement, are not used for advertising or cross-site tracking, and can be cleared in browser settings. Global Privacy Control or Do Not Track disables this measurement.
Essential delivery
Hosting and security providers may use strictly necessary technical mechanisms to deliver pages, balance traffic, detect abuse, and protect the service. These mechanisms are controlled by those providers and are not used by Paper Size Lab for behavioral advertising.
Your analytics choice
If separately allowed, Google Analytics may use browser storage to distinguish visits and measure pages and approved tool actions. It does not receive entered measurements, files, filenames, project names, or notes, and advertising signals are disabled. Review or change your choice.
If advertising is introduced
This notice and the privacy notice must be updated before advertising is activated. Where required, a consent interface must let visitors make an informed choice before non-essential storage or personalized advertising begins.
Your browser controls
You can inspect, restrict, or remove stored site data through your browser settings. Blocking essential security mechanisms can affect whether a site loads correctly.
