Last Lock Privacy Policy
Effective date: October 9, 2026
Last Lock is an iPhone app that helps people quit gambling. It's made by Nathan Thayer Productions LLC ("we," "us"), a Florida company. This policy explains what information Last Lock collects, how we use it, who we share it with, and the choices you have.
The short version: we collect what we need to run the app and help you quit. We never sell your information, we don't show ads, and you can delete your account and data from inside the app at any time.
If you have questions, email us at lastlocksupport@gmail.com.
Information you give us
Onboarding answers. When you set up Last Lock, we ask questions about your gambling and your goals, such as your first name, where and how often you bet, roughly how much money and time you spend on betting each week, your biggest single-day loss (as a range), your triggers and feelings, whether gambling has caused debt or affected parts of your life, your reasons for quitting, and how you heard about Last Lock. Some questions are optional, and some offer "Prefer not to say."
Your reason and photo. You can write your #1 reason for quitting and optionally add a photo. Your reason is stored with your account. Your photo stays on your iPhone. It's never uploaded to our servers. If you turn on the blocker, a small copy of the photo is shared with Last Lock's block screen on your phone so it can show it to you; that copy also stays on your device.
Your progress. As you use the app, we store your quit date, streaks, daily pledges and check-ins, urges you log, slips you record, milestones you earn, and the protection steps you complete.
Messages to Key, the AI coach. If you choose to use Key and agree to its consent screen, see "Key, the AI coach" below.
Information collected automatically
Account identifier. When you first open Last Lock, we create an anonymous account with a random ID so your progress can be backed up. We don't ask for your email address to do this.
Sign in with Apple. If you choose to back up your account with Sign in with Apple, we receive an identifier from Apple. Apple may also share an email address, which can be a private relay address if you choose "Hide My Email."
Usage analytics. We collect information about how the app is used, such as which screens are viewed, which features are used, whether permissions are allowed, and subscription events (for example, starting a trial). This information is linked to your account ID and basic device information (such as device model and iOS version). We do not send your sensitive onboarding answers (such as losses, debt, emotions, or relationships) or any of your messages to Key to our analytics provider.
Purchases. When you subscribe or buy lifetime access, Apple processes the payment. We never see your card or payment details. We receive information about your purchase (such as the plan, price, and subscription status) so we can unlock the app for you.
What stays on your iPhone
- Your photo, as described above.
- Your chats with Key. Your conversation history is stored on your device, not on our servers. You can clear it in Settings.
- The apps and websites you block. Last Lock uses Apple's Screen Time technology. When you choose apps to block, Apple gives Last Lock an encrypted reference to your selection. We can't see which apps or websites you chose, and Apple doesn't share your app usage with us.
- Some preferences, such as reminder times and your selected state for self-exclusion resources.
Key, the AI coach
Key is an optional AI coach. Before you send your first message, Last Lock asks for your consent and explains what is shared.
When you send a message, it's sent to our server, which adds context so Key can respond helpfully: your first name, your #1 reason for quitting, your triggers and feelings, your bet-free time, money and time saved, pledge streak, and unfinished protection steps, along with your recent messages. This is sent to Anthropic, the company that provides the AI model, to generate Key's reply. Anthropic processes this information under its commercial terms and privacy policy.
We don't store the content of your messages on our servers. We do keep a count of how many messages you send each day, to apply a daily limit.
Key is an AI, not a counselor, therapist, or doctor, and it doesn't provide medical, financial, or legal advice.
How we use information
We use information to:
- Run the app's features: your timer, savings, milestones, reminders, protection plan, blocker, and Key
- Back up and restore your progress across devices
- Provide and manage your subscription
- Understand how the app is used so we can improve it
- Respond to your support requests
- Keep the app secure and prevent misuse
Who we share information with
We share information only with service providers that help us run Last Lock, and only for that purpose:
| Provider | What they do | What they receive |
|---|---|---|
| Supabase | Database and account backup | Your account ID, onboarding answers, reason, and progress data |
| RevenueCat | Subscription management | Your account ID and purchase information |
| Mixpanel | App analytics | Your account ID, device information, and usage events (no sensitive answers or Key messages) |
| Anthropic | AI for Key (only if you use Key) | Your messages to Key and the context described above |
| Apple | Payments, Sign in with Apple, Screen Time, and notifications | As needed for those Apple services |
We never sell your personal information, we don't share it for advertising, and we don't track you across other companies' apps or websites.
We may also disclose information if required by law, to protect the safety of our users or others, or as part of a business transfer such as a merger or sale, in which case this policy would continue to apply.
How long we keep information
We keep your account information for as long as you have an account. When you delete your account, we delete it as described below. We may keep limited information when required by law (for example, purchase records Apple or tax rules require).
Deleting your account
You can delete your account anytime in Settings โ Delete account. When you do, we:
- Delete your account and all data stored on our servers (your onboarding answers, reason, and progress)
- Revoke Last Lock's access to your Sign in with Apple account, if you used it
- Delete your record from our subscription provider
- Request deletion of your data from our analytics provider
- Erase Last Lock's data on your iPhone, including your photo and Key chat history, and turn off the blocker
Deleting your account does not cancel your subscription. Subscriptions are managed by Apple. To cancel, go to iPhone Settings โ [your name] โ Subscriptions.
You can also email us at lastlocksupport@gmail.com to request access to or deletion of your information.
Security
We protect your information with industry-standard measures, including encryption in transit and access rules that limit each account to its own data. No system is perfectly secure, but we work to protect your information and limit what we collect.
Age requirement
Last Lock is intended for adults 18 and older. We don't knowingly collect information from anyone under 18. If you believe someone under 18 has provided us information, contact us and we'll delete it.
Your rights
Depending on where you live, you may have rights to access, correct, delete, or receive a copy of your personal information, or to object to certain uses. To make a request, email lastlocksupport@gmail.com. We'll respond within a reasonable time and won't treat you differently for making a request.
Not a medical service
Last Lock is a self-help and support tool. It doesn't diagnose, treat, or cure gambling disorder or any other condition. If you're in crisis, call or text 988 (Suicide & Crisis Lifeline) or call 1-800-MY-RESET (National Problem Gambling Helpline), both free and available 24/7. In an emergency, call 911.
Changes to this policy
We may update this policy from time to time. If we make significant changes, we'll let you know in the app or on our website before they take effect. The effective date at the top shows when it was last updated.
