Holdfast
A local VPN answers adult-site lookups on the phone. It does not decrypt HTTPS. After you pair, a partner approves an unlock, a longer pause, or uninstall.
Official site
Holdfast LLC
Holdfast LLC makes two Android apps. Holdfast filters adult sites on the device, and a partner you choose holds the pause. Steadfast is a Bible reader that can limit the apps you pick.
Accountability, on your phone
Holdfast answers blocked lookups on the device. A partner you choose can see the summaries the apps are built to share, and can approve a pause.
The apps
Steadfast
Read Scripture, listen to a chapter, and put a limit on the apps you pick. A partner can receive a weekly summary of reading and time in those apps.
The company
Holdfast LLC is the developer of Holdfast and Steadfast. The mailing address is 30 N Gould St Ste 67031, Sheridan, WY 82801. Both apps can use the same sign-in. The account is an email and password handled by Firebase Authentication. Pairing between a phone and a partner goes through a Cloudflare Worker operated for these apps.
