Privacy Policy

Effective: 17 June 2026 · Applies to all Boltworks apps

Boltworks apps are built to collect no personal data. There is no account, no analytics, no tracking, and no advertising. Everything you enter stays on your device.

Who we are

Boltworks ("we", "us") is an independent app studio. This policy covers our mobile apps, including SolSize, and this website at boltworks.app.

Data we collect

None. Our apps do not ask you to create an account or sign in. They contain no analytics, no advertising SDKs, and no third-party trackers. They request no device permissions and make no network connections to us — we operate no servers that receive your data.

Data stored on your device

Anything you enter — such as appliance loads, system profiles, and app settings — is stored locally on your device only. It never leaves your device and is never transmitted to us or anyone else. Uninstalling the app removes this data. We have no way to access, recover, or delete it for you.

Beta tester signups

If you sign up as a beta tester on this website, you submit your name and email so we can send you a Play Store invite. That information is used only to contact you about the beta and is processed by our form provider on our behalf; we do not sell or share it. Ask us to delete it anytime at hello@boltworks.app.

Purchases

If you buy a one-time unlock, the transaction is processed entirely by Google Play. We never see or store your name, payment card, or billing details. Google's handling of that purchase is governed by Google's own Privacy Policy. The app records only a local flag indicating that the unlock is active.

Children

Our apps are not directed at children and collect no data from anyone, including children.

Changes to this policy

If this policy changes, we will post the updated version on this page with a new effective date.
