Privacy Policy Effective date: September 8, 2026 SunHat is a weather-triggered reminder app for iPhone. This policy explains what data the app handles, what leaves your device, and what you can do about it. The short version: SunHat has no accounts and no servers. Your reminders, preferences and cached weather stay on your iPhone. The only data that leaves your device is the coordinate sent to a weather provider to fetch a forecast, and — in the free, ad-supported version — the data Google's advertising SDK collects to serve and measure ads. Who we are SunHat is developed by Wesley Keetch, an independent developer. Contact: weskcode@duck.com We have no account system and no backend SunHat does not ask you to sign up, sign in, or provide an email address. There is no SunHat server that receives your data, because there is no SunHat server. Nothing you create in the app is transmitted to us, and we could not retrieve it if we wanted to. Data stored on your device The following is stored locally on your iPhone using Apple's SwiftData framework, and never sent to us: Reminders you create — titles, notes, icons, colors, and the weather conditions you chose App preferences — units, quiet hours, notification limits, appearance Cached weather data — recent forecasts, so the app works offline and makes fewer network requests Saved locations — any city you pick manually This data is included in your device backup if you back up your iPhone to iCloud or a computer. That backup is governed by Apple's privacy policy, not this one. Location If you grant location permission, SunHat uses your coordinates to fetch a weather forecast for where you are. Your coordinate is sent to the weather provider only (Apple WeatherKit), for the sole purpose of retrieving a forecast. It is not sent to us, not stored on any server we control, and not used to build a profile of your movements. Location permission is optional. You can decline it and pick a city manually instead; the app works either way. You can grant reduced (approximate) accuracy in iOS Settings. SunHat will use it, though forecasts will be less specific to your exact area. You can revoke location access at any time in iOS Settings → Privacy & Security → Location Services → SunHat. Notifications If you allow notifications, SunHat sends them locally from your device when your conditions are met. Notifications are scheduled and delivered on-device through iOS. No push server is involved, and no notification content is transmitted anywhere. Weather data Weather is provided by Apple WeatherKit. Apple receives the location coordinate needed to answer the forecast request. Apple's handling of that request is governed by Apple's privacy policy: https://www.apple.com/legal/privacy/ SunHat does not fabricate weather data. When a forecast is unavailable, the app says so rather than displaying an estimated value. Advertising (free version only) The free version of SunHat displays banner advertisements supplied by Google AdMob, on the Dashboard and Weather screens only. To serve and measure those ads, Google's SDK may collect: Your device's advertising identifier (IDFA), if you permit tracking Advertising data — ad impressions, clicks, and related interaction Coarse location, device and app information, and diagnostic data, as described in Google's own documentation This data is collected by Google, not by us. We do not receive it, and we have no access to it beyond aggregate revenue reporting. Google's handling is governed by Google's privacy policy: https://policies.google.com/privacy App Tracking Transparency Before any cross-app tracking occurs, iOS asks for your permission through Apple's App Tracking Transparency prompt. SunHat does not show this prompt on your first session — it waits until you have had a chance to use the app. If you decline, nothing in the app stops working. Ads simply become non-personalized. You can change this at any time in iOS Settings → Privacy & Security → Tracking. Consent in the EEA, UK and Switzerland If you are in a region covered by the GDPR or equivalent rules, SunHat presents Google's certified consent form before any ad request is made. If you have not consented, no ad request is sent. You can reopen the consent form and change your choice at any time from Settings → Privacy → Ad Privacy Options inside the app. Removing ads entirely The optional SunHat Ad-Free subscription removes all advertising. When the subscription is active, the advertising SDK makes no ad requests at all. Subscriptions and payment SunHat Ad-Free is an auto-renewable subscription sold through Apple's App Store. We never see your payment details. Apple processes the transaction; we receive only an anonymous receipt confirming that a subscription is active. We do not receive your name, email address, billing address, or card information. Manage or cancel your subscription in iOS Settings → your name → Subscriptions, or in the App Store app. Apple's handling of your purchase is governed by Apple's privacy policy. Analytics SunHat contains no analytics SDK of its own. We do not track which screens you visit, which features you use, how often you open the app, or what your reminders say. Apple provides aggregate, anonymized App Store metrics (downloads, crash counts) that cannot be tied to an individual. Google provides aggregate ad performance reporting. Neither identifies you to us. Your rights and controls Because your data is on your device, you control it directly: What you want Where Export everything SunHat holds Settings → Privacy → Export My Data Delete everything, permanently Settings → Privacy → Delete All Data Turn location off iOS Settings → Privacy & Security → Location Services Turn off ad tracking iOS Settings → Privacy & Security → Tracking Change ad consent (EEA/UK) Settings → Privacy → Ad Privacy Options Remove ads entirely Settings → SunHat Ad-Free Remove all data at once Delete the app Deleting the app removes all locally stored data. Deletion is immediate and irreversible; we hold no copy to restore from. If you are covered by the GDPR, your rights of access, rectification, erasure, restriction, portability and objection are satisfied by the export and delete controls above, since we hold no personal data about you on any system we operate. Our lawful basis for processing location is your consent, which you may withdraw at any time by revoking the permission. If you are covered by the CCPA/CPRA, note that we do not sell or share personal information as those terms are defined. The advertising identifier handled by Google in the free version may constitute "sharing" for cross-context behavioral advertising under some interpretations; declining App Tracking Transparency, or subscribing to SunHat Ad-Free, prevents it. Children SunHat is not directed to children under 13, and we do not knowingly collect personal information from them. The app is not submitted to the App Store's Kids Category, because the Kids Category prohibits the third-party advertising the free version relies on. International transfers We operate no servers, so we transfer nothing internationally. Apple and Google may process data in countries other than yours, as described in their respective privacy policies. Data retention We retain nothing, because we receive nothing. Data on your device persists until you delete it or remove the app. Apple and Google apply their own retention periods to the data they collect. Security Data on your device is protected by iOS file-system encryption and your device passcode. All network requests use HTTPS. Because there is no account and no server, there is no credential to steal and no central database to breach. Changes to this policy If this policy changes materially, the updated version will be posted here with a new effective date, and the in-app policy will be updated to match. If a change expands what is collected, it will be described in the release notes for the version that introduces it. Contact Questions about this policy, or about your data: weskcode@duck.com
