Tinnitus Diary is built and maintained by Mohamed Hosam (referred to below as "I," "me," or "the developer"). This page explains, in plain language, exactly what the app does and doesn't do with your information.

The short version: your data never leaves your iPhone. There is no server. There is no account. There are no ads, analytics, or third-party trackers. I cannot see what you enter and I do not want to.

1. What the app stores

When you use Tinnitus Diary, the app saves the following information locally on your device:

• Tinnitus entries — date, loudness rating (0–10), the ear and pitch tags you select, symptoms, possible triggers, sleep hours, stress level, and any notes you choose to type
• Medication or supplement logs — the name you type and whether you felt it helped
• Your matched tinnitus frequency in Hz — used only on-device to generate your personalized notched-noise track
• Your tinnitus profile — the optional pitch and ear tags you can set during onboarding
• App preferences — the reminder time you set and whether you've completed onboarding

That is everything. The app does not collect your name, email address, phone number, contacts, photos, browsing history, advertising identifier, IP address, or any other personal information beyond what you explicitly enter into the journal yourself.

2. Where your data lives

On your iPhone, in the app's sandboxed storage. All entries are saved locally using Apple's SwiftData framework. Nothing is uploaded.

Tinnitus Diary does not currently use iCloud sync. If you reinstall the app or switch devices, you can move your data using the Export and Import features in Settings (described below). A future version may add iCloud sync as an opt-in feature. If that happens, this policy will be updated before the new version ships.

3. How the audio features work

The app's pitch-matching tones and masking sounds — white noise, pink noise, brown noise, rain, ocean, fan, and your personalized notched-noise track — are generated mathematically on your device in real time. No audio is streamed, downloaded, or recorded.

The app never accesses your microphone.

To play audio, the app requests an audio session from iOS using the standard playback category. This is how every audio app on iOS works and does not transmit anything off your device.
