Effective date:
This policy explains how Tinnitus Night: Sleep Sounds (the "App") handles information. The App is made by an independent developer, Abdullah Iskifoglu ("we", "us"). The App is built local-first: your diary and health-related entries are stored on your iPhone and never reach us.
The short version
- No account, no sign-in, no ads, and no tracking across apps or websites.
- Your check-ins, notes, tone results and listening history are stored only on your iPhone. They are not synced to iCloud and not sent to us or anyone else.
- The App sends anonymous crash reports (Sentry) and, unless you turn them off in Settings › Share anonymous usage data, a few anonymous usage events (PostHog). Neither includes your diary, tone, notes or tags.
- Feedback you choose to send in the App reaches us by email, with your email address only if you add it.
- If you subscribe, Apple handles the payment and our subscription provider, RevenueCat, receives an anonymous ID and your purchase history. It never receives health information.
- We do not sell or share personal information, and we do not use it for advertising.
1. Information stored on your iPhone
To work, the App keeps the following on your device:
- Check-ins: your daily rating of how much tinnitus bothered you, an optional loudness rating, tags you choose and optional notes.
- Tone results: the frequency you matched, which ear, the sound type and the individual match attempts.
- Listening history: when you played sounds, for how long, and the name of the mix.
- Saved mixes and lesson progress.
- Preferences: reminder time, maximum volume, appearance, app icon and onboarding status.
This information is protected by iOS Data Protection (it can't be read while your iPhone is locked). It is excluded from iCloud and computer backups and is not synced to iCloud. We have no servers that receive it, and we cannot see, access or recover it.
Evening reminders and the free-trial reminder are scheduled locally by iOS on your iPhone. They are not sent through any server. You can turn them off at any time in the App or in iOS Settings.
2. Information that leaves your iPhone
Information leaves your device only for in-app purchases, crash reports, anonymous usage events and feedback you choose to send:
| Who | What they receive | Why |
|---|---|---|
| Apple (App Store) | Your Apple Account and payment details, handled entirely by Apple. We never see your name, email or payment card. | Processing purchases, subscriptions, refunds and family sharing. |
| RevenueCat, Inc. (our subscription service provider) | A random, anonymous app user ID; purchase and subscription records (product, price, dates, trial status, App Store transaction identifiers); and technical information sent with each request (app version, iOS version, device model, App Store country, language and IP address). | Checking whether your Pro subscription is active, restoring purchases and preventing fraud. |
| Functional Software, Inc. (Sentry), EU data region (Frankfurt) | Crash and error reports: the type of error, where in the App's code it happened, the screen that was open, app and iOS version, device model, and a random session identifier for crash-free rates. Messages, notes, tone values, URLs with parameters and any other content are removed on your iPhone before sending. No user identifier is set, and IP addresses are not stored. | Finding and fixing crashes and errors. |
| PostHog, Inc., EU Cloud (Frankfurt) | Nine anonymous events with a random ID that isn't linked to you: onboarding finished, tone finder started, a tone finder step by name, tone finder finished (sound type only), paywall or welcome offer shown, purchase started or finished (plan name only), check-in saved. Never the frequency, levels, ratings, notes or tags, and no person profiles, screen recordings or location lookup. You can turn this off in Settings › Share anonymous usage data. | Seeing where new users get stuck, so we can make the App clearer. |
| Cloudflare, Inc. (our feedback relay) and our email provider | Only when you send feedback (Settings › Send feedback): your message, your email address if you add one, a random feedback code made on your iPhone (for example TN-7K2Q9M), app and iOS version, language and plan type (free, trial, monthly, yearly or lifetime). Never your diary or tone. Cloudflare passes the message to our inbox as an email and keeps nothing; to limit abuse it counts requests per hour under a one-way hash of the IP address, deleted after an hour. | Reading and answering your feedback. |
We have configured RevenueCat without attribution, advertising identifiers or custom attributes, so it receives no check-ins, notes, tags, tone results, listening history or any other health information. RevenueCat acts as our service provider (processor) under its data processing terms. See RevenueCat's privacy policy and Apple's privacy policy.
If you have turned on Share with App Developers in iOS Settings, Apple may share anonymous crash reports and usage statistics with us through App Store Connect. This is controlled by you in iOS Settings › Privacy & Security › Analytics & Improvements, and it does not include your diary.
3. What we don't collect
- No name, email, phone number or account.
- No location, contacts, photos, microphone recordings or Apple Health data.
- No advertising identifiers (IDFA), no advertising or attribution SDKs and no tracking across apps or websites. The only analytics are the anonymous events in section 2, which you can turn off.
- No sale or sharing of personal information, for advertising or otherwise.
4. Backups you create
You can export an encrypted backup file to move your diary to a new iPhone. The file is encrypted on your device with a password you choose (AES-GCM with a key derived from your password). We never see the password and cannot recover it or your backup if the password is lost. You decide where to save or send the file (for example Files, iCloud Drive or AirDrop). Wherever you store it is subject to that service's own terms and privacy policy; the file stays encrypted.
5. Retention and deletion
- On your iPhone: data is kept until you delete it. Use Settings › Delete all data in the App, or delete the App, to remove everything the App stored on your device.
- RevenueCat: purchase records are kept for as long as needed to provide the subscription and to meet legal, tax and accounting obligations. You can ask us to delete them (see Your rights).
- Apple: purchase records are kept by Apple under its own policy.
- Sentry: crash and error reports are kept for up to 90 days.
- Feedback: emails stay in our inbox as long as needed to answer and follow up, and are deleted on request. Your email address is used only to reply to you.
- PostHog: anonymous events are kept for up to 12 months. Turning off Share anonymous usage data stops new events and resets the random ID on your iPhone.
Deleting the App or your data does not cancel a subscription. Cancel in iOS Settings › your name › Subscriptions.
6. Legal bases (EEA and UK)
Where the GDPR or UK GDPR applies, we rely on:
- Performance of a contract to provide and verify your subscription and to restore purchases.
- Legitimate interests to prevent fraud, answer support requests, fix crashes, and understand where the App is unclear through anonymous events (which you can turn off at any time).
- Legal obligation to keep transaction records where tax or accounting law requires it.
Your health-related entries are processed only on your device, under your control. We do not collect or receive them.
7. Your rights
Depending on where you live, you may have the right to access, correct, delete or receive a copy of personal information about you, to object to or restrict processing, and to withdraw consent. Residents of California and other US states with privacy laws have similar rights, and we will not discriminate against you for using them.
Because the App has no accounts, the only personal information we can reach is the anonymous purchase record at RevenueCat. To make a request, email us. You can find your support ID in the App under Settings › About › Support ID; including it lets us locate your purchase record. For payment or Apple Account data, contact Apple directly.
If you are in the EEA or UK, you also have the right to complain to your local data protection authority.
8. Consumer health data (US states)
This section is our consumer health data privacy policy under laws such as Washington's My Health My Data Act, Nevada SB 370 and Connecticut's consumer health data provisions.
- What health-related data the App handles: the check-ins, tags, notes, tone results and listening history described in section 1.
- Where it comes from: only from what you enter in the App.
- How it is used: only on your iPhone, to show your history, patterns and sounds shaped to your tone.
- Collection by us: none. This data is not transmitted to us or to any third party.
- Sharing and sale: we do not share or sell consumer health data. No third party or affiliate receives it.
- Your rights: you can view and delete all of it yourself in the App at any time. You can also contact us with any question or request.
9. International transfers
Sentry and PostHog store data in their EU regions (Frankfurt). RevenueCat is based in the United States and may process purchase records there. Where required, such transfers rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses and the UK addendum.
10. Security
On-device data is protected by iOS Data Protection and stays out of device backups. Backups you export are encrypted with your password. Network requests to RevenueCat, Sentry and PostHog use encrypted connections (HTTPS). No method is perfectly secure, but keeping your diary off our servers means there is nothing on our side to leak.
11. Children
The App is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has made a purchase, contact Apple for a refund and contact us to delete the purchase record.
12. Changes to this policy
If we change how the App handles information, for example by adding optional iCloud sync, we will update this page and the effective date above before the change takes effect. If a change is significant, we will also tell you in the App.
