Privacy
This page explains what the game keeps on your device, what it sends to our server, and what other companies may collect. It is written to match what the game's code does.
The short version
There are no accounts. We never ask for your email address or your real name. Your browser gets a random ID, and the game uses it to keep your progress and your board row apart from everyone else's.
While you play, the game sends a log of gameplay events to our server, linked to that random ID. We use it to see how the game is played and to fix problems.
No ads are shown on this site at the moment. The Google AdSense code is on our pages because Google is reviewing the site. When ads are switched on, Google and its partners may use cookies to choose ads. The Advertising section explains this and how to opt out.
What is kept on your device
The game keeps its data in your browser's local storage. Only this site can read it.
- Your random ID, made on your first visit. It is not based on your device, your network, or anything about you.
- Your display name, if you enter one.
- Your progress: best level and score, biomass earned and spent, boosters, saved levels (up to eight), and the days you played.
- A few settings: sound on or off, and whether you have seen the guided start and other tips.
- A copy of the world board, and a note when a score is still waiting to be sent.
Your browser also keeps a copy of the game's own files, so the game can run offline.
What is sent to our server
Our server is a small program that runs on Cloudflare. The game sends it the following:
| What | When | Why |
|---|---|---|
| Your random ID | On every visit, when the game loads the board and checks for purchases, and with every batch of gameplay events | To find your own row and purchases, and to link events from the same browser |
| A visit ID | With every batch of events | To group the events of one visit. A new one is made on each visit. |
| Gameplay events | During play, up to 20 at a time | To see how the game is played: levels started and ended, each shot and any warning shown, lives lost and why, boosters used, which panels were opened and for how long, settings changed, and which screen was open when you left |
| Device and visit facts | Once per visit | Screen width and height, pixel density, whether the game runs as an installed app, how many days have passed since your first visit, and whether you came back a day or a week after it |
| Display name, best level, biomass earned by playing, and the marks for boosters used or eased levels | When you enter a name, and when a run ends after that. Nothing is posted without a name. | To show your row on the world board. The board list the game downloads also contains each listed player's random ID, so the game can find your own row. |
| Country | Added by Cloudflare's network, not by the game | Kept at country level only |
What we do not collect
- No IP addresses are written to our own records.
- No precise location. Country is the finest level we keep.
- No email address, phone number or real name.
- No contacts, photos, microphone or camera.
- We do not sell your personal information.
Hosting
The site is hosted by Netlify and reaches you through Cloudflare's network. Like every web host, they handle your IP address to deliver the pages and to protect the site from attacks. Their privacy policies: Netlify, Cloudflare.
Advertising
No ads are shown on this site at the moment. The Google AdSense code
(publisher pub-3899465888591544) loads on every page because Google is
reviewing the site for advertising. This page will say so when ads are switched on.
When ads are shown:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google's Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
Google explains what it collects through its code on sites like this one in How Google uses information from sites or apps that use its services. We do not give your display name, your board row or your progress to any advertising company.
Your choices about advertising
- If you are in the European Economic Area, the UK or Switzerland, you will be asked through Google's consent message before advertising cookies are used. You may refuse, or change your answer later. Refusing means you see non-personalized or limited ads.
- Wherever you live, Google's Ads Settings and www.aboutads.info (linked above) let you turn off personalized ads.
- Your device or browser may offer its own controls, such as settings that block third-party cookies.
Payments
Paid packs of biomass are not on sale at the moment. If they are offered, card payments happen on Stripe's own checkout page, so the game never sees your card details. Stripe may ask for your email address and billing details under its own privacy policy. Our server keeps a record of what was bought, linked to your random ID, and a restore code that lets you move purchases to another device.
Cookies
The game itself sets no cookies. It keeps its data in local storage, which you can remove by clearing this site's data in your browser. Google uses advertising cookies once ads are shown, as explained above.
Deleting your data
Open the menu (☰) during play, choose Delete my data, then tap it again to confirm. This deletes your row on the world board and the gameplay events stored for your random ID on our server. Events not yet sent are dropped, and no more events are sent during this visit. Your display name is also cleared on this device, so your results are not posted again unless you enter a name again.
If you play again on a later visit, gameplay events are recorded again under the same random ID. To stop that, clear this site's data in your browser: your next visit then gets a new random ID, and everything this site kept on your device is gone.
The button does not reach data held by Google or other advertising companies, and it does not remove purchase records. For those, or for anything else, write to us at the address below.
How long we keep data
Board rows are kept while the board exists, or until you delete them. There is no automatic deletion schedule for gameplay events yet: they are kept until you use Delete my data or until we delete old events.
Children
The game is not directed at children under 13, and we do not knowingly collect personal information from them. The game does not ask anyone's age. If you believe a child has entered a display name that should be removed, use Delete my data on that device, or write to us.
Your rights
Depending on where you live (for example the UK, the European Economic Area, or a US state with a privacy law), you may have rights to access, correct and delete personal data about you. We treat the random ID as personal data even though it identifies a browser rather than a person. Delete my data deletes directly; for anything else, write to us.
Changes
If what the game collects changes, this page changes with it, and the date below moves.
