About Gratitude, LLC
We are an independent iOS development studio with one guiding conviction: your personal health data belongs to you — not to us, not to advertisers, not to anyone else. Everything we build starts from that principle.
Our Story
Gratitude, LLC was founded in 2025 with a straightforward mission — build health tools that respect the people who use them. When we looked at the landscape of period-tracking apps, we kept seeing the same pattern: free apps funded by selling intimate health data, or subscription services that lock your own cycle history behind a paywall and store it in the cloud.
We thought there had to be a better way. So we built SyncMate: an iOS period tracker that does everything you would expect a modern cycle app to do — adaptive prediction, six-phase wellness guidance, calendar view, daily notifications — without ever sending a single byte of your cycle data off your device.
No account required. No cloud sync. No data sold. Just your cycle, on your phone, in your control.
Privacy-First, No-Cloud Philosophy
We made a deliberate architectural choice early in development: SyncMate would store all data exclusively in iOS's on-device persistence layer, with no network calls, no backend servers, and no telemetry. That is not a marketing claim bolted on after the fact — it is how the app was designed from the first line of code.
What this means in practice:
- No account or sign-in — there is nothing to create because there is no server to store it on.
- No cloud sync — your data lives in the iOS app container on your device. When you delete the app, the data is gone. We never had it.
- No third-party analytics or ad SDKs — we ship zero tracking libraries. There is nothing to opt out of.
- No data sold or shared — we have no data to sell. This is not a policy choice we could reverse — it is a technical reality.
We believe this is how health apps should work, especially those dealing with reproductive health — a category of data that carries particular sensitivity and deserves particular protection.
Our Expertise
SyncMate reflects hands-on experience with the full iOS development lifecycle — from product design through App Store submission and ongoing support.
- iOS native development — SyncMate is built with SwiftUI and Swift, targeting modern iOS. We work within the Apple ecosystem daily: HealthKit considerations, App Store review guidelines, iOS data storage patterns, and local notifications.
- Cycle science integration — The six-phase model and adaptive prediction algorithm in SyncMate are grounded in established menstrual cycle physiology. Phase definitions, hormonal context, and wellness suggestions were developed with reference to peer-reviewed cycle science literature.
- App Store presence — SyncMate is published on the iOS App Store, meeting Apple's review standards for health applications, privacy nutrition labels, and data practice disclosures.
- Privacy engineering — Designing a fully on-device app is an active engineering challenge, not a passive default. We made deliberate trade-offs (no cross-device sync, no web access) in order to make a genuine privacy guarantee rather than a conditional one.
- User support — We provide direct email support at [email protected] and maintain this support site with detailed FAQs, wellness guides, and documentation.
