Privacy policy

Effective 11 October 2026

This policy covers Slatewise LLC's apps, this website, and the messages you send us. Each app has its own section below saying exactly what that app does with information, and the same section is published on its own at that app's privacy page.

The short version. What you type into our apps stays on your iPhone. The only time anything you've written reaches us is when you choose to send us feedback, and then we receive just that message, plus your email address if you'd like an answer. Our apps have no accounts, no ads, no analytics and no tracking. Purchases go through Apple, and our subscription provider, RevenueCat, receives an anonymous ID and your purchase record so it can confirm what you bought. This website counts its visits with Cloudflare Web Analytics, which sets no cookies and gives us totals rather than anything about you. If you buy from our shop, Gumroad runs the checkout and takes the payment, and passes us the order details we need to deliver it.

BackupsIncluded in your iPhone's iCloud or computer backup

Stubwise has no account, no ads, no analytics SDK and no usage tracking. The hours and pay you log stay on your iPhone. The only information that leaves it is the record of a purchase, and any feedback you choose to send us.

What stays on your iPhone

Everything you enter is stored in the app's own storage on your iPhone: your jobs, hourly rates and overtime settings, your clock-ins, shifts, breaks, tips and notes, any pay stub amounts you type into the Paycheck Check, and your reminder times and other preferences. None of it is sent to us or to anyone else; if you send us feedback, we receive only the message you write. Pay and overtime are worked out on the phone itself, and since we never receive this information, we can't read it, recover it or delete it for you; it's yours to manage on your device.

Backups

Like most app data, this information is included in your iPhone's backup, whether that's iCloud Backup or a backup to a computer, depending on how your iPhone is set up. Those backups are made and kept by Apple or by your own computer, not by us. The app doesn't sync between devices, but restoring a backup onto a new iPhone brings your hours with you.

Reminders and exports

Shift reminders are local notifications, scheduled and delivered on your iPhone, and their contents stay on your iPhone, with no notification server in between. When you export a timesheet, the file is made on your iPhone and goes only where you send or save it through the share sheet.

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

  • On your iPhone: deleting the app deletes its data. Copies inside earlier backups remain until those backups are deleted, which you control in your iPhone or iCloud settings.
  • At RevenueCat: purchase records are kept while they're needed to provide Premium, restore purchases, and keep our legal, tax and accounting records. You can ask us to delete them. Since they aren't linked to your name, we may ask for a detail from your Apple receipt, such as the order ID, so we can find them.
  • At Apple: Apple keeps its own record of your purchases under its own policies.

BackupsIncluded in your iPhone's iCloud or computer backup; Backup files you export, kept wherever you save them

MudMath has no account, no ads, no analytics SDK and no usage tracking. Your measurements, jobs, prices, customer details and logo stay on your iPhone. The only information that leaves it is the record of a purchase, and any feedback you choose to send us.

What stays on your iPhone

Everything you type into MudMath 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 (if you send us feedback, we receive only the message you write), and since we never receive it, we can't see it, recover it or delete it for you. MudMath doesn't sync between devices, so if you'd like a copy somewhere else, MudMath 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. MudMath 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 MudMath 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:

Keeping and deleting

  • On your iPhone: deleting the app deletes its data, apart from any backup files you exported yourself.
  • At RevenueCat: purchase records are kept while they're needed to provide Pro, restore purchases, and keep our legal, tax and accounting records. You can ask us to delete them. Since they aren't linked to your name, we may ask for a detail from your Apple receipt, such as the order ID, so we can find them.
  • At Apple: Apple keeps its own record of your purchases under its own policies.

BackupsIncluded in your iPhone's iCloud or computer backup

Loafsona has no account, no ads, no analytics SDK and no usage tracking. Your photos never leave your iPhone unless you share a card yourself, we don't analyze anyone's face, and the only information that leaves the phone is the record of a purchase, and any feedback you choose to send us.

Your photos

When you take a photo in Loafsona, it's resized on your iPhone and checked, on your iPhone, by Apple's built-in Vision framework, which reports only whether there's a face-shaped area in the picture and where it is. The app uses that to decide between a person's bread and a no-face result, and to center the optional photo on your share card. Nothing about how anyone looks is measured, stored or used. The bread is drawn at random.

The photo is kept in the app's temporary cache for the current reading and deleted when you take the next one. It's never uploaded, never saved to your photo library by the app, and never stored in your Bread Box. We don't create, collect or keep face geometry, face templates or any other biometric identifier.

If you choose to put your photo on a share card and share it, the card goes wherever you send it through your iPhone's share sheet. That's you sharing your own picture, and we don't receive a copy.

What stays on your iPhone

Your Bread Box (which bread each reading gave, any name you typed and the date), your vibe-check answers and your settings are stored on your iPhone only. 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.

Backups

Like most app data, your Bread Box and settings are included in your iPhone's backup, whether that's iCloud Backup or a backup to a computer, depending on how your iPhone is set up. Those backups are made and kept by Apple or by your own computer, not by us. Photos aren't included, since the app deletes each one when you take the next.

Purchases

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:

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.

What we don't do

  • Upload or store your photos.
  • Analyze faces, or infer age, gender, ethnicity or anything else about anyone. The result is random.
  • Show ads or use the advertising identifier.
  • Use an analytics SDK or a crash-reporting service. RevenueCat gives us aggregate purchase reports, such as how many people bought each pack, which is why the App Store label lists Purchases under Analytics.
  • Track you across other companies' apps or websites.
  • Sell or share personal information.

Children

Loafsona is a general-audience entertainment app, and it doesn't collect personal information from anyone, including children. The one thing it can send us is a feedback message someone chooses to write, with an email address only if they add one, and if a parent tells us a child sent one, we'll delete it.

Keeping and deleting

  • On your iPhone: deleting the app deletes its data. Copies inside earlier backups remain until those backups are deleted, which you control in your iPhone or iCloud settings.
  • At RevenueCat: purchase records are kept while they're needed to provide what you bought, restore purchases, and keep our legal, tax and accounting records. You can ask us to delete them. Since they aren't linked to your name, we may ask for a detail from your Apple receipt, such as the order ID, so we can find them.
  • At Apple: Apple keeps its own record of your purchases under its own policies.

People in Illinois, Texas, Washington, California, the EU, the UK and elsewhere have specific rights over biometric and personal data. Loafsona collects no biometric data, and the only personal information it ever sends us is an email address you choose to add to feedback, but you're always welcome to ask us about either.

Templates bought on Etsy are sold and delivered through Etsy, which takes the payment and handles the download under Etsy's privacy policy. Etsy passes sellers the details needed to complete an order, and we use those details only for that order, for helping you with it, and for our business records. Buying from our own shop is covered under Buying from our shop. The template files themselves contain no tracking of any kind. If you send us feedback about a template, the feedback section below says what we receive.

This website

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.

We count visits to this website with Cloudflare Web Analytics, which Cloudflare provides as the site's host. A small script from Cloudflare reports which page was viewed, the page that linked to it and how quickly it loaded, and Cloudflare works out the visitor's country; what reaches us is only totals, such as how many people looked at a page this week and where they came from. It sets no cookies and stores nothing in your browser, and Cloudflare says it doesn't use your IP address, your browser's details or anything else to single you out; Cloudflare's privacy policy covers how it handles that data. Apart from Gumroad's checkout on the shop pages (see Buying from our shop), it's the one script on our public pages, and it counts visits to the website only, so it has nothing to do with our apps, which contain no analytics SDK at all.

The one cookie this site sets itself is a sign-in cookie on a private page we use to manage it, which visitors never see. On the shop pages, Gumroad may set cookies of its own, as Buying from our shop explains.

When you send us feedback

Each of our apps and templates, and this website, has a way to tell us what you think: a short form in the app, or the feedback page here. Nothing is sent until you press Send, and what we receive is what the form shows you: your message, which product it's about, the kind of message you chose, and your email address if you'd like us to answer. In an app, the form can also include a few app details (the app's version, your phone's model and system version, your language setting, and which screen you were on), and it shows you those before you send, with a switch to leave them out. There's no account, and nothing that identifies your phone.

Messages are kept in a database Cloudflare runs for us, apart from everything else, and only we read them. We use them to fix what's broken and to decide what to make next, and we use your email address only to answer that message. To keep the form from being flooded, we also keep a scrambled form of your IP address, made with a one-way hash and a key that changes every day, so it can't be turned back into your address or matched from one day to the next. We erase the hashed address after 7 days. The messages themselves are deleted after a year, or sooner if you ask; write to privacy@slatewisestudio.com with the reference the form gave you, and we'll find it.

Please don't put pay stubs, passwords or anything sensitive in a message. Describing what happened is always enough.

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.

Buying from our shop

The shop pages sell our workbooks and templates through Gumroad, which processes each purchase as the merchant of record. To show the checkout, those pages load Gumroad's checkout script from gumroad.com, and that script loads its own style and code files from Gumroad. Fetching them sends Gumroad the standard details any website receives, such as your IP address, your browser type and the page you're on, and Gumroad may set its own cookies. No other page on this site loads anything from Gumroad.

When you choose Buy, Gumroad's product page opens over ours, and the checkout runs on Gumroad. Everything you type there, such as your email address and card details, goes to Gumroad and its payment processors and never passes through this website. Gumroad handles it under Gumroad's privacy policy.

After a purchase, Gumroad passes us the details of the order: what you bought, the price and any tax, your email address, your name and ZIP or postal code if you gave them, the page that sent you to the product, and the card type with its last four digits (never the full card number). We use them only to deliver that order, to help you with it, and for our business records, and we keep them as long as tax and accounting rules require.

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, the order details Gumroad passes us when you buy from our shop, any emails you've sent us, and any feedback 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, to understand how many people subscribe, and to read and answer your feedback and keep the form free of abuse. Information handled by RevenueCat or Gumroad is processed in the United States, and Cloudflare may store and process feedback in the United States and the other countries where it runs its network.

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, and send feedback to us, only over encrypted connections. Each service provider we use, RevenueCat included, is bound to protect your information at least as well as this policy does. No system is perfectly secure, so 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.
