Privacy through noncollection
How the local-only tools work
The strongest privacy protection is often not collecting the information in the first place.
Designed not to submit
Your typing stays in the page you are using.
Crohns247’s worksheet tools are designed not to submit your entries to our servers or save them in cookies, URLs, analytics or browser storage. The tool pages contain no form action, no upload function and no network connection used to transmit worksheet entries.
No persistence
No localStorage, sessionStorage or IndexedDB.
No tool analytics
Worksheet routes use a policy that blocks analytics and network connections.
User-controlled output
You decide whether to print or save a PDF on your own device.
Your device still matters
Local-only does not mean nothing can ever be retained.
Your browser, device, extensions, password managers, printer or a locally saved PDF may retain copies outside Crohns247’s control. Browser restoration features can sometimes preserve page contents even when a website does not intentionally save them.
When finished
Use Clear Everything, close the page, secure or destroy printed copies, and manage any PDF you saved. On a shared device, avoid leaving the page open or the PDF accessible.
Technical boundaries
What is intentionally absent from tool pages
- No account, login or user profile
- No form submission, fetch, XHR, WebSocket or beacon transmission
- No cookies, localStorage, sessionStorage or IndexedDB for worksheet values
- No third-party fonts, videos, social embeds, chat widgets or advertising
- No analytics or third-party error reporting on worksheet routes
- No worksheet values placed in URLs
- No service worker or offline cache
Important limits
Crohns247 is not a secure medical-record system.
The tools are for short-term organization on your own device. They are not a patient portal, personal health record, HIPAA service, encrypted vault or substitute for the systems used by licensed providers.
Standard hosting and security infrastructure may process general request data—such as the page requested, date and time, IP address or browser information—but worksheet contents are not included in the URL and are not submitted by the tools.
