SiteCalc has no account, no ads and no analytics. Your measurements, jobs, prices, customer details and logo stay on your iPhone, and the only information that leaves it is the record of a purchase.

What stays on your iPhone

Everything you type into SiteCalc is stored on your iPhone: dimensions and results, saved jobs, your material prices, your business details and logo, and the names and addresses of any customers you put on an estimate. None of it is sent to us, and since we never receive it, we can't see it, recover it or delete it for you. SiteCalc doesn't sync between devices, so if you'd like a copy somewhere else, SiteCalc Pro can export a backup file for you to keep wherever you choose.

Your logo and photos

When you add a logo, you pick one image and only that image is used. SiteCalc keeps it on your iPhone for your estimates and doesn't read the rest of your photo library.

Files you share, and links you open

An estimate PDF, a CSV or a backup file goes only where you send it, whether that's Mail, Messages or Files, and SiteCalc keeps no copy anywhere else. The source links behind each calculation open the manufacturer's or standards body's own website, and that site's privacy policy applies there.

Purchases and subscriptions

Paid features are sold as in-app purchases through the App Store, and Apple takes the payment, so we never receive your name, your card, your billing address or your Apple Account. To check a purchase and unlock the paid features, the app uses RevenueCat (RevenueCat, Inc.), which receives the following:

What RevenueCat receives, and why
WhatWhy
A random, anonymous app user ID that the app creates. It isn't your name, your email or your Apple Account, and it isn't the advertising identifier.To know which purchases belong to this installation, and to restore them.
Your purchase history for this app: the App Store transaction and receipt, the product, its price and currency, and dates such as when a trial started, renewed or was cancelled.To confirm the purchase with Apple, unlock what you paid for, prevent fraud, and show us subscription reports, such as how many trials turn into subscriptions.
Basic technical details: device model, iOS version, app version, language, storefront and currency, and the IP address your connection comes from.Any request over the internet carries these, and they're needed to connect and validate the purchase.

RevenueCat never receives anything you type into the app. It processes this information on our behalf in the United States, and its own practices are described in the RevenueCat privacy policy. Apple's handling of your purchase is covered by Apple's privacy policy.

Keeping and deleting

This website

These pages are static. They set no cookies, and they load no analytics, no third-party scripts and no web fonts from anyone else's servers. The one exception to the cookie rule is a private sign-in page we use to manage this site, which sets a sign-in cookie for us and is never shown to visitors. The site is hosted by Cloudflare, which handles standard request information, such as your IP address, your browser type and the page you asked for, in order to deliver and protect the site, and may keep it in logs for security and reliability. We don't use that information to identify you.

When you email us

If you write to us, we receive your email address and whatever you choose to send, and we use it only to answer you. We keep that correspondence for as long as we need it to help you and to keep ordinary business records, and then delete it. Please don't send pay stubs or other sensitive documents; describing the problem is enough.

What we don't do

Children

Our apps are tools for working adults and aren't directed to children under 13. We don't knowingly collect personal information from children, and if you believe a child has sent us some, write to us and we'll delete it.

Your choices and rights

Depending on where you live, you may have the right to ask for access to, a copy of, correction of, or deletion of personal information we hold about you, to object to or restrict how we use it, and to complain to a data protection authority. We'll honour those requests wherever the law gives you these rights, and we won't treat you differently for making one. Write to privacy@slatewisestudio.com. In practice, the only personal information we hold is the purchase record at RevenueCat and any emails you've sent us.

If you're in the United Kingdom, the European Economic Area or Switzerland, we rely on the performance of our contract with you to check purchases and provide paid features, and on our legitimate interests to prevent fraud and to understand how many people subscribe. Information handled by RevenueCat is processed in the United States.

Security

What you keep in our apps is protected by your iPhone's own security, such as your passcode and data protection, and our apps talk to RevenueCat only over encrypted connections. No system is perfectly secure, which is one more reason we collect as little as we can.

Changes to this policy

If we change this policy, we'll update this page and its effective date. If a change affects what an app collects, such as adding a new service, we'll say so in that app's update notes before it takes effect and update its privacy details on the App Store.
