Privacy

Last updated October 21, 2026.

My apps keep what you enter on your iPhone, and none of them has accounts. The one thing that leaves the phone is a Noisy Neighbor ordinance lookup, which sends the city or ZIP code you type.

This website

clinttustison.com has no analytics, cookies, ads, accounts or forms. It is hosted on Cloudflare, which keeps standard request logs, such as IP address, browser and the page requested, to run and protect its service. See Cloudflare's privacy policy.

tenminutemath.com, dailychengyu.com, noisyneighborhelp.com and psmfdietplan.com are separate sites. Where a site has its own privacy page, that page covers the site.

Asking about your data or deleting it

Because the apps store your data on your phone, I don't have a copy of it. You can delete it yourself by deleting the app. Copies can stay in your iCloud or computer backups of the phone until those are replaced or deleted.

If you email me, I keep that email so I can reply. You can ask me to delete our emails at any time.
