Privacy Policy

Lowtide Locks · last updated 17 October 2026

Lowtide Locks is a puzzle game for iPhone, made by Nguyen Van Lam (contact: lamnv260398@gmail.com). It does not ask who you are, and it does not collect or sell any data about you.

What stays on your device

• Your progress: which locks you have opened, which you opened at par, and how many hints you hold.
• Whether you have bought the Full Estuary, and the store transaction numbers already delivered, so a purchase is never counted twice.

This is stored on your iPhone only. Nothing is sent to us or to any server. Deleting the app removes it.

What we do not do

• No account or sign-in.
• No advertising and no ad networks.
• No analytics, crash reporting or tracking of any kind.
• No access to your contacts, photos, location, camera or microphone.

Purchases

Chapter 1 is free. The Full Estuary unlock and hint packs are sold through the App Store and handled entirely by Apple under its own privacy policy. We receive no payment details or personal information; the game only learns from the store which purchases exist on your Apple account.

Children

The game collects no personal information from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page with a new date.
