Strata — Terms of Service
Strata is a game. It is played on a phone, it keeps its progress on that phone (and, if you sign in, on our server too), and it sells the rest of the game and double tickets through your app store. These terms say what you can expect from it and from us.
1. Agreeing to these terms
By installing or playing Strata you agree to these terms. If you do not agree, do not use the game. Strata is published by BrotherAI ("we", "us"). These terms are in addition to the terms of the app store you installed from.
2. Who may play
You must be old enough to hold an account with the app store you installed from, and old enough to make a purchase there if you choose to. Signing in requires a Google or Apple account under those providers' own rules. Strata is not directed to children under 13.
3. What Strata is and is not
Strata is a single-player digging game: you dig finds out of the ground, clean them and show them in a museum you build. In particular:
- Most of it plays without a connection. The boards, visits and loans between museums, the seasonal exhibits and the cloud save use our server; signing in is optional and only keeps your progress in the cloud.
- Its numbers (coins, time dust, levels, depths) are game values with no cash value, and cannot be transferred, sold or exchanged.
- What other players see of yours is set out in section 4 of the Privacy Policy: a name and a score on the boards, and your museum if you open it. Choose a name you are happy for anyone to see.
4. Purchases
The first three dig sites and the museum can be played without paying, with no time limit. Sites 4 to 10 and the Bottomless pit need the Full Game, bought once; each of those sites is still reached by digging. Double Tickets doubles the ticket price for good. The Supporter Pack holds the Full Game, Double Tickets and the night museum decor set. Gems, sold in packs and also given by the weekly challenge, buy time and looks: a team home now, a cleaning or a study finished now, an hour of the museum's takings now (up to a limit each day), a decor set. No purchase gives a find or changes a dig.
Purchases are made through your app store, under its terms, and refunds are handled by the store. A refunded purchase is taken back in the game, and what you dug stays. A refunded gem pack takes its gems back, below zero if they were spent. Purchases come back on a new device with Restore purchases. Gems are part of your save and move with a cloud save.
5. Your data
Your progress and settings are stored on your device. If you sign in, a copy is also kept on our server under your account; what the game sends us is described in the Privacy Policy.
The practical consequence is important: we can only restore what reached the cloud. If you never sign in, or the last sync did not complete, whatever your own device backup does not cover is gone when the game is uninstalled or the device is lost. Saves are never merged: when one account is played on two phones, the game keeps one save and, if both have moved on, asks you which. The purchases you paid for stay either way and come back with Restore purchases.
6. Acceptable use
Do not attempt to reverse engineer, decompile or tamper with the game or its server beyond what your local law expressly permits, and do not attempt to obtain purchases without paying for them, or a cloud save that is not yours. The game and its content (code, artwork, sound, text) are ours and are licensed to you for personal, non-commercial use, not sold.
7. Availability and changes
We may change, add or remove features in future versions, including the balance of digs, upgrades and prices, and we may stop publishing Strata. Our server may be unavailable at times and may be discontinued; the game keeps working from the save on your phone, while the boards, visits, loans and seasonal exhibits wait for the server. If we discontinue the game, the version installed on your device keeps working offline as long as your operating system supports it.
8. Disclaimer of warranties
Strata is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose or non-infringement. We do not warrant that the game or its server will be uninterrupted or error-free, or that the game will run at any particular frame rate on any particular device. Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.
9. Limitation of liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, nor for lost data or lost progress, arising from your use of Strata. Our total liability for any claim relating to the game is limited to the amount you paid for it in the 12 months before the claim.
Nothing in these terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or for fraud.
10. Changes to these terms
We may update these terms. Material changes will be reflected on this page with a new "Last updated" date before the version they apply to ships. Continuing to play after that means you accept the updated terms.
11. Governing law
These terms are governed by the laws of Vietnam, without regard to conflict-of-law rules. This does not remove any protection you have under the mandatory consumer law of the country you live in.
