Trenchline Terms of Service

Last updated: 2026-10-22

1. Acceptance

By downloading, installing, or playing Trenchline: Zombie Defense ("the game"), you agree to these Terms of Service. If you don't agree, don't use the game. Trenchline is operated by Keyao Zhu, an individual based in Vancouver, British Columbia, Canada — "we"/"us" below refers to Keyao Zhu.

If you downloaded the game from the Apple App Store, Apple's Licensed Application End User License Agreement also applies: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

2. The game

Trenchline is a single-player tower-defense game. We license it to you for personal, non-commercial entertainment. We may update, change, or remove features over time.

3. Virtual items

The game sells these virtual items for real money, through the Apple App Store or Google Play:

• Gold is the currency of a game run. It is used to build and upgrade defenses and to revive your headquarters during that run. When a run ends (your headquarters falls, you win the final wave, or you choose "Restart Run"), Gold you bought and haven't spent carries over to your next run, up to the amount you bought during that run. Gold earned in play is used up when the run ends. Gold you spend is used up when you spend it.
• Ordnance Points are used in the Armory for permanent upgrades. They stay with your progress between runs.
• The Starter Pack (offered once, for a limited time) is a bundle of Ordnance Points and Gold, delivered like the items above.
• The Commander Pack is a one-time purchase that stays yours: it gives Ordnance Points at once, the optional video ads' rewards without watching an ad, and extra Ordnance Points from wave milestones. It can be restored on another device with the same Apple ID or Google account (Restore Purchases on the Commander Pack page).

The game can also show optional rewarded video ads (from version 1.0.1); you only see one when you choose to watch it for a reward.

Virtual items have no real-world monetary value, can't be exchanged for cash, and can't be transferred to another person. They are a limited license to use content in the game, not property you own.

Game progress, including virtual items, is stored on your device. From version 1.0.1 your lasting progress is also backed up to your own iCloud (iOS) or Google Play Games (Android, when you're signed in) and can be restored on a new phone or after reinstalling (Settings > Cloud Save). A run in progress, and progress that was never backed up, can't be restored if you uninstall the game, reset your device, or move to a new phone.

4. Purchases and refunds

• Payment is charged to your Apple ID or Google Play account when you confirm the purchase.
• Refunds are handled by Apple or Google under their own policies — Apple: https://support.apple.com/en-us/118223 · Google Play: https://support.google.com/googleplay/answer/15574897. We cannot issue refunds directly.
• If you paid for something and it didn't arrive, email us with the date and the order number from your store receipt and we'll help.
• We may change prices of virtual items; changes don't affect purchases you already made.

5. Acceptable use

You agree not to reverse-engineer, decompile, or modify the game, cheat by altering its files or memory, or use the game in any way that violates applicable law.

6. Disclaimers

THE GAME IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE GAME WILL BE ERROR-FREE OR UNINTERRUPTED.

7. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF THE GAME. OUR TOTAL LIABILITY FOR ANY CLAIM RELATED TO THE GAME IS LIMITED TO THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR US$100, WHICHEVER IS GREATER. THESE LIMITATIONS DO NOT APPLY TO DAMAGES CAUSED BY OUR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, OR TO THE EXTENT SUCH LIMITATIONS ARE NOT PERMITTED BY APPLICABLE LAW.

8. Changes to these Terms

If we make a material change to these Terms, we'll update the "Last updated" date above and mention it in the app's update notes. Continuing to play after that means you accept the revised Terms.

9. Governing law

These Terms are governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein, without regard to conflict-of-law principles. This does not override any consumer-protection rights you have under the mandatory law of the country or state where you live.
