Privacy Policy
This page explains what information SFRCalc collects, how it's used, and how advertising works on this site.
The calculators themselves
The numbers you type into a calculator — purchase price, rent, expenses, and so on — are processed entirely in your own browser. They are not sent to SFRCalc or stored on our servers, and if you close the tab that data is gone. The single exception is deliberate: if you have an account and choose Save this property, the figures in that scenario are sent to us and stored, so that you can open them again later. Nothing is saved unless you click save.
Advertising and cookies
This site displays ads served by Google AdSense. Google and its partners may use cookies or similar technology to serve ads based on your visits to this and other websites. This is standard third-party ad targeting — SFRCalc doesn't control which ads appear or how Google's targeting works.
You can see and adjust how Google personalizes ads for you at adssettings.google.com, and read Google's own explanation of how it uses data at policies.google.com/technologies/partner-sites.
Affiliate links
Some links on this site are affiliate links to lenders, insurers, or other tools. Clicking one may let that company know you came from SFRCalc, subject to their own privacy practices. See our advertising & affiliate disclosure for more.
Analytics
We may use basic, aggregated analytics (such as page-view counts) to understand which calculators and articles are useful and where the site has problems. This data is not tied to your name or used to build a profile of you individually.
Information you give us directly
If you email us, we'll have your email address and whatever you wrote — used only to respond to you, not shared or sold.
Accounts and saved properties
Accounts are optional. Every calculator and article on this site works the same whether you are signed in or not, and nothing is gated behind signing up.
If you create one, we store your email address, a cryptographic hash of your password (never the password itself, which means we cannot read it or recover it for you), and the date you signed up and last signed in. If you sign in with Google instead, we ask Google only for your email address and an account identifier — not your Google password, your contacts, your files, or anything else in your Google account, and we cannot see them.
When you save a property we store the address you type, the name you give the scenario, and the figures you entered in that calculator. We store this so the feature works; we do not sell it, share it with advertisers, use it to target ads, or look at individual accounts' deals except where we have to in order to fix a fault you have reported.
Signing in sets one cookie. It holds a random session identifier — not your email or password — and exists only to keep you signed in. It is not used for advertising or tracking, and signing out deletes it.
You can delete any saved scenario or property at any time from your saved properties page, and deleting a property deletes its scenarios with it. That page also has a button that deletes your entire account — email address, saved properties, scenarios and sessions — immediately and permanently. We keep your data until you delete it or ask us to.
Children's privacy
This site isn't directed at children, and we don't knowingly collect information from anyone under 13.
Your choices
You can use most browsers to block or clear cookies at any time. Doing so may make ads less relevant but won't affect how the calculators work, since they don't depend on cookies. Depending on where you live, you may have additional rights over data collected about you (for example, under GDPR or CCPA) — contact us if you'd like to exercise any of those.
Changes to this policy
We may update this policy as the site changes. The "last updated" date above reflects the most recent revision.
