Privacy Policy

SAT Locker · Last updated November 5, 2026

This policy explains what the SAT Locker app for iPhone collects, why, and the choices you have. We do not sell your information for money and we do not show ads in the app. We advertise the app on other platforms, and if you allow tracking when your iPhone asks, information from the app is linked to those ads, as explained under Ads and tracking.

Information you give us

• Your study plan: your test date, your most recent score and whether it was an SAT or PSAT score, your goal score, the college you picked, and about how much time you spend on social media each day.
• Your settings: how many right answers unlock your apps, how many minutes an unlock lasts, whether sound effects are on, and which reminders are on and at what time.
• If you sign in with Apple: an identifier that Apple gives us for your account and, if you choose to share it, your email address. Apple lets you hide your real email address.
• If you sign in with email: your email address and a password. The password is stored by our database provider in a protected form, and we never see it.
• If you take the quiz on our website: your first name and email address, which you give before you see your plan. If you buy a plan there, we also receive the email address you use at checkout. We never see your card details.
• If you start or join a challenge with friends: the nickname you choose and the name of each challenge you start.
• Messages you send to our support email.

Information created when you use the app

• An account identifier that the app creates the first time you open it, before you sign in. It lets us save your progress without asking for your name or email.
• Your practice: which questions you answered, whether each answer was right, when you answered, the questions in your review list, how many times you unlocked your apps and when you used an emergency pause.
• Usage events, such as which screens you open, whether you finished the setup, whether you allowed Screen Time and notifications, and whether a purchase was completed. We use them to find what is confusing in the app and what to improve.
• Your level, which comes from your projected score estimate. We keep the highest level you reached.
• Your iPhone's time zone, so that your streak and your daily numbers follow your local day.
• Your subscription status: which plan you have, whether it is in a free trial, and when it renews or ends. Apple, or the website checkout, sends this to RevenueCat, which tells our servers.
• Technical records that our servers keep for security, such as the IP address and the time of each sign-in.

What we don't collect

• We can't see which apps you lock. You choose them in Apple's Screen Time picker, and Apple gives the app a code that only works on your iPhone and doesn't reveal the app names. That code stays on your iPhone.
• We don't see how long you use other apps or what you do in them. Screen Time information never leaves your iPhone.
• We don't collect your location, contacts or photos, and we only read your advertising identifier if you allow tracking when your iPhone asks.
• We don't receive your card number or other payment details. Payments are handled by Apple or, for plans bought on our website, by Stripe.

Ads and tracking

We advertise SAT Locker on platforms such as Meta (Facebook and Instagram) and TikTok, and we use a company that measures our ads. Your iPhone asks whether you allow tracking before the app connects to that company.

If you allow tracking, the app sends that company your iPhone's advertising identifier and vendor identifier, your device model, system version, screen size, memory size, time zone, language and region, your account identifier, your email address if your account has one, the setup screens you reach and when you open the subscription screen. It also receives your IP address, as any server does when a device connects to it. The app keeps a marker in your iPhone's keychain that stays after you delete the app, so that a reinstall doesn't count as a new install.

That company uses this information to connect your install and your purchases to an ad you clicked, and it sends those results to Meta and TikTok, with your email address hashed. Those platforms use them to measure our ads and to show our ads to people similar to those who install and subscribe, under their own privacy policies.

If you don't allow tracking, your iPhone blocks the app's connection to that company, so none of the information above is sent. Apple may still report ad results to the ad platforms in aggregate through its own system, which doesn't identify you.

Whatever you choose, RevenueCat tells that company about subscription purchases, renewals and cancellations, with the account identifier, so that our sales reports are complete. Without your permission those purchases are not linked to your device or to an ad.

You can change your choice at any time in your iPhone Settings, under Privacy & Security, then Tracking. Deleting your account clears the identifiers the app keeps on your iPhone, but it doesn't reach that company's servers. To delete what it holds about you, write to support@satlocker.app and we will ask it to delete it.

How we use information

• To run the app: your plan, your projected score estimate, your streak, your review list, the lock on the apps you picked and your reminders.
• To back up your progress, so it comes back if you reinstall the app or sign in on a new iPhone.
• To run challenges with friends. The people in the same challenge see your nickname, your level, how many questions you got right during the challenge and your percentage of right answers. They don't see your name, your email or anything else about you. You can leave a challenge at any time, and you can report or block someone from the leaderboard.
• To know whether your subscription is active, and to answer your questions.
• To keep the service secure, for example by checking that new accounts are created by people and not by automated programs.
• To understand how the app is used and improve it.
• To measure our ads and show them to more people who may want the app, as explained under Ads and tracking.

Who processes data for us

• Supabase stores your account and your progress on servers in the United States and sends account emails, such as sign-in codes.
• Apple provides Sign in with Apple, In-App Purchase, Screen Time and notifications.
• RevenueCat receives your subscription purchases from Apple or from our website and tells our servers whether your subscription is active. It knows your account identifier or, for a website purchase, your email address, not your name.
• Stripe processes the card payment when you buy a plan on our website. It receives your payment details and email address. We only learn whether the payment worked and when the plan renews or ends.
• Cloudflare Turnstile checks, without showing you a puzzle, that a new account is being created by a person. To do that it looks at technical information from your device and connection, such as your IP address.

These companies use the information only to provide their service to us. We may disclose information if the law requires it or to protect the safety and rights of people and of the app.

The company that measures our ads, Meta and TikTok are covered under Ads and tracking.

How long we keep it, and deleting it

We keep your information while your account exists. You can delete your account at any time in the app: Settings, then Account and privacy, then Delete account. This deletes your account and your progress from our database right away. Copies in our backups are removed when those backups expire. If you signed in with Apple, deleting your account also removes SAT Locker from the apps that use your Apple Account.

Deleting your account does not cancel a subscription bought through Apple, so cancel it first in your iPhone Settings. For a plan bought on our website, we also keep the email address and the status of that purchase for as long as the subscription runs and afterward for our payment records. To cancel it, write to support@satlocker.app.

To get a copy of your information or to correct it, write to support@satlocker.app. California residents and others with similar rights can use the same address.

Permissions you can turn off

• Reminders: in the app's Settings or in your iPhone Settings. Reminders are scheduled by the app on your iPhone.
• Screen Time access: in your iPhone Settings, under Screen Time. Without it, the app can't lock your apps.

Children and teens

SAT Locker is not for children under 13, and we don't knowingly collect information from them. If you believe a child under 13 is using the app, write to us and we will delete the account.

If you are under 18, you need permission from a parent or guardian to use the app.

Changes and contact

If we change this policy in a way that matters, we will update the date at the top of this page.
