Otter Element Privacy Notice

Effective date: October 26, 2026 · Last updated: October 26, 2026

This notice describes what the Otter Element game does with data. It is written from how the game and its ranking service actually work, not from a general template.

About this notice

Otter Element is published by Otterly Games. In this notice, “the developer” means Otterly Games. The notice covers the Otter Element Android game and the Otter Element ranking service it talks to.

  • Our general Privacy Policy covers the Otterly Games website, its contact form and the learning games Clock Master, Math Tank and Space Academy. What it says about accounts, cloud copies of progress, public player profiles, ads and purchases describes those products, not Otter Element.
  • The short playable preview on the Otter Element page of otterlygames.com runs in a web browser. It is not the Android app, and this notice does not describe it.

The short version

  • Otter Element has no account, email or password. Your campaign is saved on your device.
  • You can delete your online records yourself. In the app, go to Settings → Your data → Delete my data. For an install with a secure online identity this deletes your online records, then erases your campaign and settings from the device. You do not need to contact anyone. Older installs, and installs whose secret is missing, cannot delete online records from the app; see Deleting your data.
  • Online rankings and Lab Siege use a random install ID, not your name. You may choose a public name; if you do not, the game generates one. These belong to the game: they are not your Google account, your email or your Android advertising ID.
  • The only ads are rewarded ads that you choose to watch. Google’s ad SDK handles them and Google’s consent form asks for your choices where it is required.
  • Purchases go through Google Play. The game never sees your card details. To check a paid score, the game sends the purchase’s store token to the ranking service, which passes it to Google Play; see Purchases.
  • Erasing only this device from Settings does not delete online records. See Deleting your data.

What stays on your device

These stay in your browser or app storage and are not sent anywhere unless a section below says so:

  • your campaign save and its backup checkpoints;
  • game settings, accessibility choices, your Lab Siege and event plans and progress, and your profile choices;
  • for online features, the install ID and, on installs that have one, a secret that proves the install is yours to the ranking service;
  • records of paid orders, which let purchases be restored and stop one purchase from being granted twice;
  • optional reminders, if you turn them on and allow notifications. They are scheduled on your device and are not sent through a server.

The game does not run analytics or advertising trackers of its own. Google’s ad SDK, described below, is separate.

Export save writes a file with your campaign only. It does not include the secret above, and it does not include Lab Siege plans, progress, checkpoints, uploads waiting to be sent or paid supplies. Saves from older versions of the app may still hold purchase or recovery data that the app cannot confirm is safe to transfer. Export is then blocked; the app says so and changes nothing. Import and Undo change only the campaign. They do not carry Lab Siege data with them, and Lab Siege data left on the device is not guaranteed to be the data the imported or restored campaign was using.

Lab Siege data from older versions of the app that is not marked for the install it is running under is kept once on this device only, in a private area that is not tied to any install ID. Your Lab Siege progress and supplies stay across reloads and changes of install ID. While Lab Siege is in that mode, the game does not upload scores, including any waiting to be sent, does not move campaign potions or rewards, and does not start new purchases. Lab Siege data that is marked for the current install works as normal.

Rankings and Lab Siege (online)

If you play an event, Lab Siege or rankings, the app talks to the Otter Element ranking service, which runs on Microsoft Azure. Two kinds of install exist:

  • Secure identity. When a campaign starts from nothing (for example the first launch, or after the device has been erased) and the service can be reached, the service issues a new random install ID and a secret. The secret stays on your device in its own storage, outside your save and its export. The service keeps only a one-way hash of it.
  • Older install. An install that already existed keeps the random ID the device made for itself. That ID is not secret. These installs are never converted to a secure identity, and a new campaign that starts while the service cannot be reached also gets a device-made ID.

The app sends:

  • the app ID, your install ID, and the game and app versions; on secure installs, the secret as well, when the app signs in;
  • your chosen public name, if you set one;
  • a record of how a run or Lab Siege hour was played, so the service can check that a score is real. This includes paid Lab Siege actions (product, tier and element) and a short number derived from the store order ID.

The service stores this as: a player record (name and replay checks), your best scores, leaderboards, Lab Siege state (roster, wallet and purchase counters), purchase fingerprints, and a profile record (your name and the time of its last change or activity). For secure installs it also stores the install ID, the hash of the secret and when the identity was created. Daily limits are counted only as totals, without install IDs.

Public boards show your public name, score and rank, and a public Otter ID. The public name is optional and visible to everyone, so choose one that does not identify you. The Otter ID is a scrambled code derived from your install ID. It is not the install ID, but it stays the same for your install. If you have not chosen a name, the game generates one.

The service keeps rate-limit counters in memory while it runs; they are not saved or logged by the app’s code. Like any web service, the platform that hosts it may process your IP address in its own logs; see What this notice does not cover.

Ads and your choices

Otter Element shows only rewarded ads, and only after you tap to watch one. There are no banners or pop-ups. Ads come from Google AdMob through the Google Mobile Ads SDK in the Android app.

What Google may collect

To request and show an ad, the SDK sends data to Google. Google’s published disclosure for the Google Mobile Ads SDK lists the IP address, interactions with ads (such as taps and video views), diagnostic information, and device and account identifiers: the Android advertising ID (the app declares that permission), the app set ID and, where they apply, other identifiers related to accounts signed in on the device. The SDK may also use cookies or similar technologies. Google’s own privacy policy governs what it does with that data. These identifiers are Google’s and your device’s; they are separate from the install ID and public name used by rankings. The game does not ask for your Google account or email, and does not add your name, install ID or progress to ad requests.

Your choices

  • Where required, Google’s consent form (User Messaging Platform) asks for your choices before any ad is requested. If consent is not obtained, the game does not request ads.
  • If you have not agreed to personalised ads where that consent applies, the game asks for non-personalised ads.
  • Settings → Your data → Ad privacy choices reopens the form when Google says privacy options are required for you. It is shown only when it can do something. If the check fails, the game says so and offers to check again; ads are not requested unless Google’s consent check allows them.
  • Hide ad offers in Settings hides the ad buttons only. It does not change your consent choices.
  • You can also change Android’s own ad settings (for example, reset or delete the advertising ID) on your device.

Outside the Android app (for example in a web browser) the game simulates ads in its own screen and sends nothing to Google for them; the ad choices row does not appear there.

Purchases

Paid Lab Siege supplies are bought through Google Play Billing. Google handles payment and your payment details; the game never receives them.

To keep rankings fair, the ranking service checks paid play against Google Play. When a build talks to the ranking service, a real purchase works like this:

  • Before the Google Play screen opens, the app asks the service whether it is ready to check purchases, sending the app ID and your session. If the service is not ready or cannot be reached, the real purchase screen does not open.
  • The app attaches a one-way code derived from the app ID and your install ID to the Google Play purchase.
  • After the purchase, the app sends the order details and the purchase’s store token to the service. The token is a credential for that purchase. The service passes it to Google Play to confirm the purchase. The service does not keep the raw token in its records or write it to its own logs; it keeps a one-way fingerprint so the same receipt cannot be reused. The token still travels in the request to Google, and the hosting platform’s own diagnostics are outside what the app controls (see What this notice does not cover).

This applies to both secure and older installs. For an older install, checking a new purchase does not turn it into a secure identity and does not give it the right to delete online records.

Purchases made before this check existed, or without the one-way code, cannot be matched to Google Play automatically. They are not treated as verified and stay pending, and the developer has no automatic way to assign them to an install. Your progress and supplies are kept.

A paid score that has not been confirmed with Google yet stays private and does not appear on public boards. Your progress and supplies are kept either way. When Google confirms the purchase, the score is published automatically.

Deleting your data does not erase your Google account, your Google Play purchases or Google’s records of them. Use Restore purchases after a device is erased.

How long things are kept

On your device

Until you erase it, uninstall the app or clear its storage.

Public profiles

A profile that has been inactive for 90 days is removed by the ranking service, along with its ranking and Lab Siege copies. Reading your profile, changing your name and accepted scores count as activity. This is the service’s default setting.

Event scores

Event records, including scores waiting for purchase confirmation, are kept for the event retention period, currently 8 weeks. This is not the same as the 90-day profile setting, and not all data expires after 90 days.

Security records

Records that stop a deleted install or a used store receipt from being used again are kept without an automatic expiry. They are not public and do not hold your name. See Deleting your data.

Deleting your data

The normal way to delete your online data is to do it yourself in the app, without writing to the developer. Contacting the developer is only for installs that cannot do this in the app, and for privacy questions.

In the app: installs with a secure online identity

Settings → Your data → Delete my data asks the ranking service to delete your online records. Nothing on your device is erased until the service confirms. When it does, the app erases your campaign, settings and plans from the device and restarts. If you are offline or the service is busy, nothing is erased and you can try again. Trying again is safe even if an earlier attempt reached the service but the app never heard back.

The service deletes your chosen name, player and score records, leaderboard entries, Lab Siege state and purchase grants for this app. It keeps:

  • a one-way fingerprint of each used store receipt, so it cannot be redeemed again;
  • a record that this install was deleted, with its ID, the time, and a hash of its secret.

Public board responses fetched earlier can show the old entry for up to about 45 seconds. New responses are not cached. Your Google Play purchases stay with your Google Play account; use Restore purchases afterwards.

Older installs, or a missing secret

Older installs use an ID that is not secret, so the service cannot tell whether a request really comes from the owner. The same applies if the secret that proves ownership is missing or does not match. The app therefore does not try to delete these online records: Delete my data says so and offers only to erase this device. If you want the online records deleted, ask the developer (see Contact); the developer may need to ask for evidence of ownership. You can still erase your device from Settings, but that does not delete the online records, and the app then no longer holds the ID it would need to ask for them to be deleted. The 90-day inactivity rule in How long things are kept applies to these profiles too.

Erasing only this device

If the ranking service is not available, the app can erase this device alone. It says plainly that the online records stay.

What this notice does not cover

  • Google’s handling of ad data, Google Play purchases and your Google account is governed by Google’s own terms and policies.
  • The ranking service runs on Microsoft Azure. The platform’s own diagnostic logs and backups are outside what the app can erase, and the developer cannot promise their deletion or state their retention.
  • Deleting online records does not erase game data saved on other devices, your billing account or provider transaction records. In the app, Delete my data also erases the device you are using, once the service confirms the online deletion.

Contact

Publisher: Otterly Games. For a privacy question about Otter Element, or to ask for the online records of an older install (or an install that has lost its secret) to be deleted, use the contact form on otterlygames.com and choose the topic “Otter Element privacy or data deletion”. You do not need the form to delete an install with a secure online identity: use Settings → Your data → Delete my data, described under Deleting your data. The form is for parents, carers and other adults and asks for an email address so that a reply is possible. The form service and how a message is handled are described in the general Privacy Policy. This notice does not list an email address or postal address of its own.

Please do not put passwords, purchase tokens, receipts, save files or any secret kept by the game in a message, and leave out children’s names, school, birth date, photos and other identifying details, as the form asks.
