App name: Brain Forge — Cognitive Training Suite
Package (Android applicationId for this build): com.totuslife.brainforge
This policy describes Brain Forge for Android com.totuslife.brainforge. A separate listing may exist under com.brainforge.
This policy supports transparency for distribution on Google Play (including Play Console Data safety). What we process depends on which features you use.
Brain Forge is a cognitive training app with brain games, puzzles, and chess multiplayer. It includes 19 training games (250 levels each), including Totus Word Quest (English crossword answers with bilingual clues where available), Factor Flow, Neuro-Link Logic, and Word Search Quest. New boss mini-games include checkers, bug trivia, Bomb Squad, peg solitaire, and algebra challenges. We are committed to protecting your privacy.
Any on-device summaries—including cognitive score, training credits, regional "brain" visualizations, charts, percentages, or neuroanatomical labels—are provided strictly for entertainment and general educational purposes. They are not factual medical data or clinical measurements. Brain Forge is not a medical device and does not diagnose, treat, monitor, alleviate, or prevent any disease or health condition.
Brain Forge does not show third-party ads, sell your personal information, or use advertising / marketing-analytics SDKs to track you across other companies’ apps for ad profiling. We do not declare the Android advertising ID permission for ad use; the Play build blocks com.google.android.gms.permission.AD_ID in app configuration.
Online features use Google Firebase as a service provider when you use them—see below. That processing is for operating multiplayer and Arcade economy features, not for selling data for ads.
| Area | Mostly on device | Firebase (when feature used) |
|---|---|---|
| Training games | Yes | No full per-game state upload |
| Arcade credits / unlocks | Partial | Anonymous user document fields |
| Chess multiplayer | Local chess points | Room document for sync |
| Settings / language / break reminder | Yes | Not for those preferences |
Firebase (Google LLC) provides Authentication (anonymous), Firestore, and Cloud Functions for Chess and Arcade. Purposes: anonymous session, room state, credit/unlock fields, server-confirmed spend, anti-tamper. We do not use Firebase here for ad personalization.
Firebase privacy · Google Privacy Policy
Communication with Firebase typically uses encryption in transit (e.g. HTTPS/TLS). No security method is perfect; see also the Terms of Service.
Firebase data may be processed in the United States and other regions. If you use optional online features from the EEA, UK, or Switzerland, personal data may be transferred outside those areas. Transfers typically use appropriate safeguards described in Google’s documentation (for example Standard Contractual Clauses) under Regulation (EU) 2016/679 (GDPR) and related UK/Swiss rules. See Google Cloud & the GDPR and Firebase privacy.
On-device training games do not require transfers to Firebase beyond what is described for local storage.
Plain-language summary for obligations similar to the EU General Data Protection Regulation (GDPR) and the UK GDPR where they apply—not a full legal analysis.
Controller / processor: The developer on the Google Play listing is typically the controller for processing we control; Google (Firebase) generally acts as a processor for those cloud services.
Legal bases (Article 6): On-device gameplay and preferences — contract (providing the app) and legitimate interests in stable operation. Optional Chess / Arcade cloud sync — contract (features you use) and legitimate interests in preventing abuse of credits and unlocks. We do not perform solely automated decisions with legal or similarly significant effects (Article 22).
Your rights may include access, rectification, erasure, restriction, portability, objection (where based on legitimate interests), withdrawal of consent where applicable, and a complaint to a supervisory authority (EEA authorities via the EDPB).
How to exercise rights: Contact the Play listing (developer email). We respond as required by applicable law where we can verify and fulfill the request.
Children: Where Article 8 GDPR applies, parents or guardians should supervise optional online features; contact us via the Play listing for child-related requests where the law applies.
We do not generally publish a separate EU/UK DPO or representative; use the Play listing unless we add another address.
The following is stored on your device for these items (not uploaded as described here):
Most of this data stays on your phone. Clearing app data or uninstalling the app will remove the local copy.
Arcade training credits (optional cloud mirror): When you open the Arcade or after you earn scores, the app may sign in with Firebase Anonymous Auth and write a small document under users/{anonymousUid} in Firestore: training credit balance, processed cognitive total (for credit math only), and which Arcade titles you have unlocked. This is not your name, email, or contacts. If you are offline, credits may update only on-device until the next successful sync.
Expansion and offline-first titles (Totus Word Quest, Factor Flow, Neuro-Link Logic, Word Search Quest): These games run on your device like other training games. Progress and scores use the same local storage pattern and are not uploaded to our servers for those titles. Totus Word Quest crossword answers stay English/Latin letters; localized clue lines are bundled on-device where available.
Brain Forge includes an in-app Language selector. All 50 languages shown in the list ship with bundled interface text for the app shell—menus, stats, Settings, Arcade catalog names, level-selection chrome, and translated titles and short descriptions for each training game. English remains the fallback only if a future update omits a string for a locale. Word-based puzzle content (word-search letter grids, crossword grids and clues, word-scramble target words, hangman, riddles, and similar modes) may still use English or Latin letters, or English clues and answers, in some locales where curated word banks are not yet used. Puzzle content is not fetched from our servers when you change language. Language choice is on-device and does not create an account or send your preference to Firebase.
The Chess multiplayer feature uses Firebase (Google) to allow you to play with a friend using a room code:
Firebase is operated by Google. Their privacy policy applies to data processed by Firebase:

The Arcade offers additional unlockable mini-games (abstract strategy, word and logic puzzles, geometry, reflex / brick-style paddle games, and skill games—the catalog may grow). Each title stays locked until you spend earned training credits to unlock it (server-confirmed when online). It uses the same Firebase project with anonymous authentication. Firestore may store under users/{anonymousUid}: integer training credits, processed cognitive total derived from on-device scores, and unlocked catalog ids. Security rules restrict client-side changes to earned credits. When you spend credits to unlock a title, a Cloud Function (Firebase Callable, same project) confirms the unlock and updates that document on the server; no extra personal identifiers are added. Credits are earned from brain-training scores; there is no separate in-app purchase currency for these unlocks. Purpose: earned access to Arcade titles; optional consistency when using the same anonymous session.
Brain Forge uses minimal permissions:
Some levels include bonus challenges that may use your device’s text-to-speech (spoken hints or encouragement) or vibration / haptics. That feedback is produced on your device; we do not record your voice, store audio for upload, or send haptic or speech data to our servers.
Brain Forge suits a broad audience. It has no third-party ads and is not built to profile users for ads. We aim to align with Google Play Families policies when your target audience includes younger users: no in-app ads, no advertising-ID use for marketing here, and optional online features limited to Firebase as described—not open social networks or public feeds.
Optional Chess multiplayer syncs the board between two people who share a room code. Players may optionally send pre-selected emoji reactions (not free-text messaging). There is no friend list or public profile. Parents, guardians, and educators may wish to supervise sharing of room codes.
We do not knowingly collect names, emails, phone numbers, or contact lists from children through the app. On-device data is game progress, scores, and optional settings. Firebase Anonymous Auth does not ask for a child-specific profile; see above for technical identifiers.
Publishers should keep Play Console App content (target audience, Data safety, Families/ads declarations) consistent with this policy.
If you are a parent or guardian with concerns, contact us via the Play listing; we may delete relevant Firebase-held data where feasible.
The U.S. Children’s Online Privacy Protection Act (COPPA) and the FTC’s implementing rule address personal information collected online from children under 13. FTC resources include:
What we do not collect in-app from children: We do not ask for a screen name, email, phone number, or postal address through the app. We do not show third-party ads or interest-based advertising (see Ads, marketing tracking, and sale of data above).
Optional online features: If Chess multiplayer or Arcade sync is used, Firebase Anonymous Auth may assign a persistent identifier and store gameplay-related fields in Firestore as described above—supporting the feature, not marketing or open social networking. Core training games work on-device without these features.
Parents and guardians: Contact us through the Google Play listing (Developer contact) to request access, deletion, or cessation of collection of child-associated information where COPPA applies. We take commercially reasonable steps to respond, including deleting or anonymizing Firebase data we can reasonably identify.
Service providers: See Firebase Privacy Information for Google’s processing.
We may update this policy; the Last updated date changes. Material updates may be noted in-app (e.g. About) where practical.
