Privacy Policy

Who this applies to

This policy covers the Yellphone website and the Yellphone mobile app. Yellphone is operated from Sweden. References to “Yellphone”, “we”, or “us” mean the operator of the Yellphone service.

The website

The current website does not offer accounts, forms, advertising, or optional analytics. We do not directly collect names, email addresses, or payment details through this website.

The site is hosted through GitHub Pages. Like most hosting providers, GitHub may process technical request data such as IP addresses, browser information, timestamps, and requested URLs for security and delivery. That processing is governed by GitHub’s own privacy documentation.

The website plays voice previews from files hosted on the same website. It does not require microphone access.

The mobile app

Microphone and speech recognition

Yellphone asks for microphone permission when you use name training or arm find mode. The app requests on-device speech recognition and uses microphone sound levels to detect a yell. Yellphone does not intentionally record, store, or upload microphone audio or speech transcripts.

Settings stored on your phone

Your chosen phone name, pronunciation variants, personality, and feature settings are stored locally on your device. Android backup is disabled for this app. On iOS, Apple may include app data in a device or iCloud backup depending on your system settings. Uninstalling removes the current device copy, but restoring a platform backup may restore local app data.

Device features

The app may use battery state, vibration, flashlight, notifications, and background audio while find mode is armed. When a reaction plays, Yellphone temporarily raises media volume and then restores the previous level. These features are used locally to make the phone easier to find and to play reactions.

Analytics and advertising

The current app does not include advertising SDKs or third-party analytics SDKs. If that changes, this policy and the applicable app-store disclosure will be updated before the change is released.

App stores and purchases

Apple and Google may process account, purchase, device, diagnostic, and refund information when you download or buy Yellphone. Yellphone does not receive your full payment-card details. Their processing is governed by their own terms and privacy policies.

Purchase validation through RevenueCat

Yellphone uses RevenueCat, Inc. to validate the one-time lifetime purchase, keep the paid entitlement active, and restore purchases. RevenueCat may process a random, pseudonymous app-user ID, store transaction and receipt data, entitlement status, store country, and limited app or device identifiers and diagnostics needed for receipt validation and fraud prevention. Yellphone does not create a RevenueCat account with your name or email address.

This processing is necessary to provide and restore the paid feature under the purchase contract and for the legitimate interests of validating purchases and preventing fraud. RevenueCat processes this information under its privacy policy. Apple or Google remains the payment processor; Yellphone and RevenueCat do not receive your full payment-card details.

Creator Reward claims

When the Creator Reward opens, a claim may require a social-video URL, view-count evidence, purchase proof, contact information, and payment details needed to issue the reward. This information will be used to review the claim, prevent abuse, make payment, and meet accounting or legal obligations. Claim instructions and any additional privacy details will be published before claims open.

Retention and sharing

Local app settings remain on the device until you clear or uninstall the app, subject to any platform backup retained under your Apple settings. Purchase and entitlement records are retained by Apple, Google, and RevenueCat as needed to validate purchases, restore access, prevent fraud, and meet legal obligations. To request deletion of data controlled by Yellphone or help with a RevenueCat deletion request, email dev@yellphone.app. Yellphone does not sell personal data. Claim information, once the program opens, will be kept only as long as reasonably needed for payment, fraud prevention, accounting, and legal requirements.

Your rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to processing of personal data. You may also have a right to complain to your local data-protection authority. To make a privacy request or ask a question, email dev@yellphone.app.

Changes

We may update this policy when the app, website, or legal requirements change. The effective date at the top shows the latest version.
