This Privacy Policy describes how the mobile applications published by Glassy Apps ("we", "us", "our") — including InterestLab and JurosLab (the "Apps") — handle information. By using an App, you agree to this policy.
We do not collect any personal information. The Apps have no user accounts, no sign-in, and do not ask for your name, email, location, contacts, or any other personal data.
Any values you enter (such as amounts, rates, and dates) and any calculations you choose to save to the in-app history are stored only on your device. We never receive, transmit, or have access to this content.
The Apps contain no third-party analytics, advertising, or tracking software. We do not build user profiles and we do not use cookies or advertising identifiers.
The Apps are designed to work fully offline. They connect to the internet only to:
Some Apps offer an optional one-time purchase (for example, "Premium"). All purchases are processed by Apple through the App Store. We do not receive or store your payment details. Purchase validation and restoration rely on your Apple ID entitlements, which are handled by Apple. Apple's handling of this data is governed by Apple's Privacy Policy.
Your saved calculations are stored locally using Apple's on-device database (SwiftData). If you have enabled iCloud or device backups, this data may be included in backups managed by Apple's operating system, according to your device settings and Apple's terms. We have no access to those backups.
You are always in control of your data. You can delete individual saved calculations inside an App at any time, or remove all of it by deleting the App from your device. Because we hold no data about you, there is nothing for us to delete on our side.
The Apps are general-purpose financial calculators and are not directed to children. We do not knowingly collect personal information from anyone, including children under the age of 13.
The only third party involved in the operation of the Apps is Apple (App Store and StoreKit). We do not integrate any other third-party service that would receive your information.
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Continued use of an App after changes take effect constitutes acceptance of the updated policy.
