Promise is built to run entirely on your own phone. There's no account to create and no server holding your data. This page explains, plainly, what the app keeps, where it keeps it, and the few small exceptions: a bit of anonymous usage data that helps us improve the app, and the information needed to process a subscription.
Everything you create in Promise is saved inside the app's own storage on your phone. It is never uploaded to a server we run, and never shared with anyone. That includes:
If you choose a step promise, for example "walk 8,000 steps", Promise asks for your permission to read your step count from Apple Health. Step count is the only Health data new promises use. If you set up an older health promise in an earlier version of the app, Promise may keep reading the data that promise needs (flights climbed, workouts, walking minutes, active calories or stand hours) until that promise is finished, and only for that purpose. This is optional, and you can change or revoke access at any time in the Health app or in your iPhone's Settings.
Profile picture. You can add your own profile picture from your photo library. Promise uses Apple's photo picker, so it only receives the one photo you pick, not the rest of your library. The picture is stored on your phone only, and you can remove it at any time from your profile. "Delete my data" removes it too.
Share card. After a kept promise you can share an "i kept my promise." picture with your streak. It is created on your phone and only goes where you send it through the iOS share sheet. Whatever app you share it to handles it under its own privacy policy.
Export. The export option creates a text copy of your journal (dates, promises, whether you kept them, and your notes) that you can copy or share. Once you send it somewhere, it's in your hands.
To understand which parts of the app work well, Promise sends a small number of anonymous signals to TelemetryDeck, a privacy-focused analytics service based in the EU. This tells us things like "how many people reached this screen" or "which answer was most commonly picked", never who you are.
These signals may include:
What this data does not include: your name or nickname, your promise text, your letter to your future self, your notes or journal, your Apple Health data, your gym plan, anything from the fresh start tracker, your profile picture, your exact location, or any advertising identifier that could be used to track you across other apps or websites. TelemetryDeck does not use IDFA, and this data is not linked to your identity.
Promise's subscriptions are purchased through Apple's App Store and managed using RevenueCat, a subscription infrastructure service that confirms a purchase went through and unlocks the features that come with it. Apple handles the payment itself; we never see your card or payment details.
Data RevenueCat may process on our behalf includes:
If you arrive through a creator's referral link, our affiliate partner InfluTo checks whether the install came from that link. If it did, the creator's referral code is added to your anonymous RevenueCat record and passed to InfluTo when you subscribe, so the right creator is credited. This is not linked to your personal identity and is never used for advertising.
Promise is not directed at children under 13, and we do not knowingly collect personal information from them. The age picker during setup starts at 13. Age and gender entered during onboarding are stored on your device and, when included in anonymous analytics, are never linked to an individual.
Because Promise has no accounts and keeps your content on your phone, you already control it: you can view it in the app, export it, or erase it with "delete my data" or by deleting the app. If you have questions about the analytics or subscription data described above, or a request under data protection law (including the GDPR, since we're based in the EU), contact us at the address below. You also have the right to complain to your local data protection authority.
If this policy changes, the update will be posted at this same link with a new effective date above.

These Terms of Use ("Terms") govern your use of the Promise: Self-Growth Tracker mobile application ("Promise" or "the App"). By downloading, installing, or using the App, you agree to these Terms and to Apple's standard Licensed Application End User License Agreement. If you don't agree, please don't use the App.
Promise helps you make and keep small promises to yourself. It includes daily promises and evening check-ins, smart promises linked to your Apple Health step count and focus time, a focus timer, a gym planner, a journal, a fresh start quit tracker, speech and memory training, and a home-screen widget. The App runs on your device with no account system, and your data is stored locally, as described in the Privacy Policy above.
Promise offers optional auto-renewing subscriptions ("Subscriptions") purchased through Apple's App Store, currently a weekly plan and a yearly plan (the yearly plan includes a 3-day free trial). By purchasing a Subscription, you agree to the following:
Deleting your data won't cancel a subscription. "Delete my data" erases your locally stored progress, but an active Subscription continues until you cancel it in your Apple ID account settings.
Promise is a personal habit tool. It is not a medical device, and nothing in it is medical, fitness, nutritional, psychological, or addiction-treatment advice.
What you create in Promise, including your promises, notes, workout plans, and profile picture, belongs to you. Because it's stored on your device, you're responsible for keeping it, for example by using the export option, and for making sure you have the right to use any photo you add. Speech training texts are provided for personal practice only.
You agree to use the App only for its intended purpose, and not to misuse, reverse-engineer, or attempt to disrupt the App or the services it relies on.
The App relies on Apple services (the App Store, Apple Health, notifications, Face ID) and on RevenueCat, TelemetryDeck, and InfluTo. The App may also link to outside resources, such as help lines. We aren't responsible for third-party services or websites, which are governed by their own terms and privacy policies.
The App, including its design, mascot, illustrations, speeches, and text, belongs to us and is protected by applicable intellectual property laws. You may not copy, modify, or distribute any part of the App without permission.
The App is provided "as is," without warranties of any kind, express or implied. We don't guarantee the App will be uninterrupted or error-free, that notifications or automatic health check-offs will always work, or that it will produce any particular outcome for you.
To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the App, including injury during exercise or loss of data stored on your device. Nothing in these Terms limits rights you have under mandatory consumer protection law.
We may update these Terms from time to time. The update will be posted at this same link with a new effective date. Continuing to use the App after an update means you accept the revised Terms.
