This policy explains what information Hand Mach Corp ("we") collects through our apps and how we use it. It applies to RentWise and ChordWatch. Wayfaith: The Glass Pilgrim collects no personal data and has its own privacy policy.
When you create an account, we collect your name, email address and password. In RentWise, you also enter information about your properties, tenants, contracts, payments and expenses. You decide what to enter.
Account and app data are stored with Google Firebase, a cloud service that encrypts data in transit and at rest. Only you and the people you invite to your account can access your data.
We use your information only to run the app: to sign you in, sync your data between devices and people on your account, and generate the reports you request. We do not sell your information, share it with advertisers or use it to track you across other apps and websites.
RentWise paid plans are purchased and billed by Apple through your Apple Account. We never receive or store card or payment details. We only keep the active plan, its renewal date and the purchased product, to unlock features for the people on your account.
Payment reminders are scheduled on your device. You can turn them off at any time in iPhone Settings.
In RentWise you can delete your account and related data at any time in More > Settings > Delete my account. You can also ask us to delete it by emailing us from the address on your account. We complete deletion requests within 30 days. For RentWise users in Brazil, see the full Portuguese privacy policy.
Our apps are not directed to children under 13, and we do not knowingly collect their information.
If we change this policy, we will update the date above and post the new version on this page.
