TACHS Prep privacy policy

Last updated: September 7, 2026

TACHS Prep: Practice Tests is made by Simple Tree LLC. It is a study app for the Test for Admission into Catholic High Schools, which eighth graders take, which means the people using it are children. We built it so that we never learn anything about them. The short version: we collect nothing, and the App Store privacy label for this app reads Data Not Collected because that is literally true.

The short version

• No account, no sign-up, no login, no email address. We don't know who you are, and there is nothing to sign in to.
• There is no analytics, no crash reporter, no advertising library and no tracking of any kind. The app has no code that sends anything to us, and we run no server that could receive it.
• Your answers, your study plan, your error journal and your scratch work are stored on your device. If you are signed in to iCloud, most of that also syncs to your own private iCloud account, which we cannot read.
• No ads. No advertising identifier. Nothing you do is profiled, scored, or sold.
• The app has exactly one way to send something out of itself, and your child controls it: the progress report, which they choose to share. It is described in full below.

No accounts

TACHS Prep has no sign-up and no login. You never give us a name, an email address, a phone number, or a password, and there is no profile on our end that anything could be attached to. When you open the app for the first time it asks one thing — roughly when your test is — so it can pace a study plan. The answer lives on your device. It is not sent to us.

The app does not talk to us

This is the part most privacy policies cannot say plainly, so we will: the app contains no networking code of our own. It makes no web requests to us or to anyone else. There is no analytics SDK, no crash reporter, no advertising library and no "anonymous usage statistics". The only third-party code in the app is SwiftMath, an open-source library that draws mathematical notation on screen; it has no networking either.

The practical consequence is worth stating: even if we wanted to know how many questions you got wrong, or which topics you struggle with, or how long you study, we could not find out. That information never reaches us.

The one thing that does travel is your iCloud sync, and it does not travel to us — it is carried by Apple's own frameworks into your private iCloud, described next.

What is stored, and where

• On your device. Your answers, your accuracy and progress, your study plan and test date, your error journal, and the handwritten working from the scratch pad. Deleting the app removes all of it.
• In your own private iCloud. If you are signed in to iCloud, your answers, your study profile and your pass sync between your devices using Apple's CloudKit, in the private database attached to your Apple Account. This is the same mechanism that syncs Notes or Reminders. We are not a party to it: we cannot read that database, we cannot list who has one, and we receive no copy. The app uses no public or shared CloudKit database. If you would rather it did not sync at all, turn iCloud off for TACHS Prep in iOS Settings and everything stays local.
• The scratch pad stays on the device it was written on. Handwritten working is deliberately not synced — it is bulky, it is per-device, and the pad only appears where there is room for it beside the question, which in practice means an iPad. It is written into the app's own storage and nothing moves it anywhere.
• Nowhere else. There is no third destination.

The two things your child can choose to send

We would rather name these plainly than let you discover them.

A name, if you want the app to use one

There is one optional text field in the app: "What should the app call you?". It is not part of setting the app up, nothing requires it, and leaving it empty simply means the app says "Good morning" instead of using a name. If you do fill it in, that name is kept on the device and in your own private iCloud alongside everything else, so it can appear in the greeting and at the top of the progress report. It is not sent to us, and the app says so on the same screen as the field.

The progress report

Your child can turn their recent practice into a one-page PDF and send it to you — that is the whole point of it. The report is assembled and rendered on the device; nothing is uploaded to produce it, and no copy comes to us. It is then handed to the standard iOS share sheet, and from that moment it goes wherever your child sends it, exactly like any other file they share. There is no automatic parent email, no server-side report, and no address for us to send one to even if we wanted to.

Permissions we never ask for

The app requests no system permissions whatsoever. It has no camera, microphone, photo library, contacts, calendar, health, Bluetooth or location access, and it cannot acquire them silently — iOS requires an app to declare each one in advance, and TACHS Prep declares none at all. If iOS ever shows you a permission prompt attributed to this app, something is wrong and we would like to hear about it.

Purchases

TACHS Prep is free to use, with a paid pass that unlocks the full question bank, the lesson library and the full-length practice tests for a year. It is a single payment with no auto-renewal — it lasts 365 days, nothing recurs, there is nothing to cancel, and there are no reminder emails, because we have no address to send them to.

The purchase is handled entirely by Apple. We never see your card, your billing address, or your Apple Account. Apple tells the app one thing: whether a valid purchase exists. Restoring a purchase asks Apple the same question again. If you want a refund, that is Apple's process, at reportaproblem.apple.com.

No ads, no tracking

There is no advertising in TACHS Prep and there will not be. The app does not use the advertising identifier, does not participate in any tracking network, and will never show you the App Tracking Transparency prompt, because it has nothing to ask permission for. Its privacy manifest declares no tracking and no tracking domains, and declares that no data is collected. The single required-reason API it uses is the ordinary one for reading and writing the app's own settings, in its own storage.

Children

This app is written for eighth graders preparing for a test they sit once, in November, so we assume children use it. That is exactly why it is built the way it is: we collect no personal information from anyone, and that includes children. There is no account to create, nothing a child is required to type, no way for a child to publish anything, and no way for a stranger to contact them through the app. There is nothing for a parent to opt out of, because there is nothing being gathered.

The app is rated 4+ and contains no advertising, no in-app browser, no links out of the study material, and no user-to-user contact of any kind. The only thing that can leave the app is the progress report, and only when your child sends it.

What we don't do

• We don't sell your data. We don't have your data to sell.
• We don't share anything with advertisers, data brokers, or analytics companies.
• We don't build a profile of you, your school, your scores, or your weaknesses.
• We don't email you, because we never learn your address.
• We don't use your work to train anything.

Your choices

• Stop the sync: turn off iCloud for TACHS Prep in iOS Settings. Your work stays on the device.
• Remove the name: clear the name field. The app goes back to a plain greeting.
• Delete everything: delete the app. To also remove the synced copy, use Settings › your name › iCloud › Manage Account Storage.
• Ask us anything: see Contact, below. You do not need an account to ask, and we will not ask who you are.

Changes to this policy

If the app ever changes in a way that affects this page — and we have no plans for it to — we will update this page and change the date at the top before that version ships. We will not quietly broaden it. If a future version ever collected anything at all, it would be described here in the same plain language, and Apple's privacy label on the App Store listing would change to match.

Contact

Questions about this policy, or about anything the app does, can go through the support page. A person reads every message, and you do not need an account to send one — we will not ask who you are.
