Privacy Policy

Last updated: February 25, 2026

Spellwork ("the App") is a children's spelling practice app developed by Gavin Vickery. Your privacy — and your child's privacy — matters. This policy explains what data the App collects and how it's handled.

Data That Stays on Your Device

All user data — profiles, spelling sheets, test results, and cached audio files — is stored locally on your device. The App has no server-side database, no user accounts, and no cloud sync. Your data never leaves your phone unless described below.

Data Sent to Third Parties

The App sends limited data to OpenAI's API (via a secure proxy) for two features:

• Photo OCR: When you photograph a spelling worksheet, the image is sent to OpenAI's Vision API to extract the word list. The image is processed in real time and is not stored by the App beyond the API call.
• Text-to-Speech: Individual spelling words are sent to OpenAI's TTS API to generate audio. The audio is cached locally so repeated requests aren't needed.

OpenAI's data usage policies apply to these API calls. See OpenAI's Privacy Policy for details. OpenAI's API data usage policy states that data sent via the API is not used to train their models.

In-App Purchases

The App offers consumable credit packs via Apple's In-App Purchase system. All payment processing is handled entirely by Apple. The App does not collect, store, or have access to any payment or billing information.

Children's Privacy

The App is designed for use by children with parental involvement. It does not:

• Require or collect personal information (no accounts, emails, or sign-ups)
• Use analytics, tracking, or advertising SDKs
• Include social features, chat, or links to social media
• Share data with third parties for marketing or advertising

The only data transmitted is worksheet photos and spelling words for the OCR and TTS features described above.

Camera Usage

The App requests camera access solely to photograph spelling worksheets. Photos are sent to the OCR API for word extraction and are not stored permanently by the App.

Data Retention

Since all data is stored locally on your device, you control it entirely. Deleting a profile or the App removes all associated data. There is nothing to delete on our end because we don't store anything.

Changes to This Policy

If this policy changes, the updated version will be posted at this URL with a new "Last updated" date.
