Privacy Policy

Last updated: September 2, 2026

This Privacy Policy applies to the websites, mobile apps and digital products operated by SanchuLLC (“we,” “us”), including Solve Math & Science, Cosmic Augur, Topos Astro Match, Decidr, RiseWell, TiffinKit and Save Them (together, the “Products”).

Our Products are designed to work without user accounts. We do not ask for a username or password, and personal inputs you enter into a Product — such as a birthdate — are stored locally on your device, not on our servers.

1. What we do not collect

SanchuLLC does not collect, receive, or store:

• Name, email, username, or password
• Account or sign-in credentials
• Payment card numbers (purchases are handled by Apple or Google)
• Personal inputs you enter into a Product, such as birthdates, on our servers
• Location, contacts, photos, or microphone audio
• Analytics, advertising, or tracking identifiers for our own use

We do not sell personal information.

2. On-device information

Some Products let you enter information (for example, a birthdate in Cosmic Augur) so the Product can generate content. That information is used only inside the Product, is stored locally on your device, is not uploaded to SanchuLLC, and is not used to create an account. You can change or delete it in the Product; uninstalling removes it.

3. Purchases

Optional subscriptions or purchases are processed by the Apple App Store or Google Play. We do not receive your name, password, or payment card details. Manage or cancel purchases in your store account settings.

4. Children

Our Products are not directed to children under 13 (or the minimum age required by the App Store or Google Play in your region). We do not knowingly collect children’s data.

5. Your choices

Because we do not collect your data on our servers, there is no account to access or delete with us. To remove locally stored information, clear it in the Product or uninstall it.

6. Changes

If our practices change, we will update this page and the “Last updated” date. Continued use after an update means you accept the revised policy.
