Privacy
Most tools on this site run locally in your browser. Files opened in the PDF editor, calculator inputs, game records and similar data are not uploaded unless a page explicitly says otherwise.
Local browser storage
Some features use local storage to remember preferences, saved feeds, game records, annotations and tool settings. You can remove this data through your browser settings.
Analytics and hosting
The site is hosted by Cloudflare and uses Cloudflare Web Analytics. Cloudflare may process basic request information needed to deliver and protect the site.
Optional Deep Swarm cloud saves
Deep Swarm can optionally upload its game save to Cloudflare so it can be restored on another device. The account uses a generated recovery code rather than a name, email address or password. The secret portion is stored only on your devices; the server stores a one-way hash. Cloud saving can be disconnected or the cloud account and save can be permanently erased from the game title screen.
Pro subscription
Pro is an optional paid add-on. Payment is processed by Stripe — this site never sees or stores your card details. We store a one-way hash of your licence key, your plan and its status, and the email address Stripe collects at checkout. The key itself is kept only in your customer record at Stripe, so it can be recovered if you lose it. See terms for billing and cancellation.
If you turn on cross-device sync, the data for the tools you sync is stored on Cloudflare against a hash of your licence key so another device can load it. Sync is off by default; with it off, tool data stays in your browser.
Usage counts
The site keeps daily totals of events such as "upgrade prompt shown" and "checkout started". These are counts only and aren't linked to you.
Advertising
This site doesn't show ads.
