Privacy First ArchitectureLast Updated: August 20, 2026

Privacy Policy

At Fair Rent, we believe your financial agreements and roommate arrangements are your private business. We engineered our rent splitting calculator from the ground up to operate with zero server-side data retention. Be fair.


1. 100% Client-Side Calculations

All calculations—including bedroom square footage proportions, amenity points, bathroom weighting, utility bills, move-in proration, and security deposit deductions—occur exclusively in your web browser using client-side JavaScript.

No Account Required: You do not need to register, provide an email address, link a bank account, or sign in to use Fair Rent.

2. How Shareable Plan Links Work

When you choose to export or share a plan, the application encodes your current inputs into the URL hash (e.g. https://fairrent.site/#plan=...).

  • No Database Storage: The plan data is stored entirely inside the link you copy. It is never uploaded to, saved in, or logged by a database on our servers.
  • Safe Sanitization: Links contain only mathematical parameters, bedroom names, and amenity flags. No personal identifiers or sensitive financial credentials are included.

3. Data We Do Not Collect

No Personal Info

We do not collect names, phone numbers, email addresses, or SSNs.

No Bank or Payment Data

We do not process rent payments, escrow funds, or collect banking credentials.

No Tracking Cookies

We do not use intrusive cross-site ad trackers or sell data to third-party data brokers.

4. Analytics & Hosting Logs

Like standard web infrastructure, basic server logs (such as IP address, browser user-agent, and requested asset paths) may be processed temporarily by our hosting provider strictly for DDoS mitigation, caching performance, and uptime monitoring.
