Privacy Policy

SPARKS ("we," "our," or "us") operates the SPARKS mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information when you use the App. By using the App, you agree to the practices described in this policy.

Account information: When you register, we collect your email address and create a user profile to store your preferences, lesson plans, and subscription status.

Usage data: We collect information about how you interact with the App, including which tools you use and session frequency, to improve the product.

Subscription and purchase data: Purchases made inside the apps are processed by the Apple App Store or Google Play and relayed to us via RevenueCat. Purchases made on this website are processed by Stripe. In every case we store only your subscription status and purchase history — we never see or store your payment card details.

Advertising data (free tiers only): Free and trial tiers show advertising served by Google AdMob. With your permission (the iOS App Tracking Transparency prompt, or the consent form in the EU), AdMob may use your device's advertising identifier to show more relevant ads; if you decline, ads are non-personalized. Paid subscribers are never shown ads and no advertising data is collected for them.

User-generated content: Lesson plans, custom word lists, question sets, and other content you create are stored in your account so you can access them across sessions. Images you upload for AI features (for example a photo of a lesson plan, or a reference image for a worksheet) are sent to our servers only to generate your requested result.

We use your information to:

• Provide and maintain the App and your account
• Process subscription purchases and verify entitlements
• Generate AI-powered lesson plans using your input
• Improve app features and fix bugs
• Send service-related communications (e.g., password reset)

We do not sell your personal information to third parties.

The App uses the following third-party services, each with their own privacy policies:

• Supabase — database and authentication (supabase.com/privacy)
• RevenueCat — subscription management (revenuecat.com/privacy)
• Stripe — payment processing for purchases made on this website (stripe.com/privacy)
• Google AdMob — advertising on free and trial tiers (policies.google.com/technologies/ads)
• Google Gemini — AI lesson plan generation (policies.google.com/privacy)
• Pinecone — knowledge retrieval for lesson planning (pinecone.io/privacy)
• Exa AI — web search for research features (exa.ai/privacy)

Your data is stored on Supabase-managed servers. We implement industry-standard security measures including encrypted connections (HTTPS/TLS) and row-level security on our database. No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

We retain your account data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law. Aggregated, anonymized usage statistics may be retained indefinitely.

How to delete your account: in any Sparks app, open the account menu (or Settings) and choose Delete account. Your account is deactivated immediately and permanently erased after a 30-day grace period — signing back in within those 30 days restores it automatically. You can also delete your account from the web at sparkskit.com/delete-account, or by emailing us at the address below, and we will process it within 30 days.

The App is designed for use by teachers, and our Terms of Service require users to be at least 18 years old. The App is not directed at children and we do not knowingly collect personal information from anyone under 18. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

Depending on your location, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data ("right to be forgotten")
• Object to or restrict processing of your data
• Data portability

To exercise these rights, contact us at the address below.

If you are located in Japan, your personal information is handled in accordance with Japan's Act on the Protection of Personal Information (APPI). You have the right to request disclosure, correction, or deletion of your personal information by contacting us. We will respond within a reasonable period as required by law.

We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the date at the top of this page. Continued use of the App after changes constitutes acceptance of the updated policy.
