Privacy Policy

BrainBoost AI Study Assistant

Effective date: September 17, 2026 · Canonical URL: brainbooststudy.com/privacy

This Privacy Policy explains how BrainBoost (“we,” “us,” or “our”) collects, uses, stores, and protects your information when you use BrainBoost: AI Study Assistant (the “App” or “Service”) on iOS, Android, and web, including https://brainbooststudy.com. By using BrainBoost, you agree to these practices.

Who we are (data controller)

BrainBoost operates the BrainBoost learning platform at brainbooststudy.com. For privacy questions, data subject requests (access, deletion, correction, portability), advertising opt-outs, or complaints, email thebrainboost2025@gmail.com with subject “Privacy Inquiry.” We are the data controller for personal information processed through the App, except where a third-party service (Apple, Google, AdMob, AdSense, Stripe, RevenueCat, OpenRouter, Composio, Microsoft, Netlify, and others listed below) processes data under its own policy.

We do not currently publish a physical street mailing address. Please contact us by email. For App Store developer contact details, see the BrainBoost product page in the Apple App Store.

1. Information we collect

Sign in with Apple or Google is optional. If you sign in, usage and subscription can be tracked across devices and reinstalls. On first launch we create an anonymous Supabase session so security, usage limits, subscriptions, and background work can function without Apple or Google sign-in.

1a. Where data is stored

On your device: Study sets, flashcard decks, study plans, chat sessions (unless incognito), notification settings, tutorial progress, academic profile, plugin connection snapshots, and imported file copies may be stored locally (including browser localStorage on web).

In the cloud: When you use AI features, sign in, subscribe, sync usage, sync AI-memory preferences, connect plugins, or start background generation, data is sent to our Supabase backend and the service providers described below. Uninstalling or clearing site data removes local data but does not automatically delete cloud records. Use Profile → Account → Delete Account or email us to request account deletion.

We do not sell personal information for money. Our advertising providers may process device identifiers and ad activity for delivery, measurement, and—where permitted and consented to—personalization. Some privacy laws define that disclosure as “sharing” or “targeted advertising.” You can decline iOS tracking permission and use applicable device or Google ad controls.

2. How we use your information

3. Data security

3a. AI and third-party AI services

What we send: When you use AI features, we send photos, questions, files, pasted text, links, image and video prompts, audio/video for transcription, academic-profile / AI-memory labels when enabled, and study-set material to our AI providers so they can return results. Podcast playback may send script text to Microsoft Edge neural voices (primary) or OpenAI neural TTS (fallback). Premium study video sends prompts and related study context through OpenRouter to ByteDance Seedance models.

Who receives it: OpenRouter and model partners such as OpenAI, Anthropic, Google, xAI, DeepSeek, and ByteDance/Seedance as available. Plugin actions are additionally sent to Composio and the connected third-party service. We do not sell your data.

How collected: When you scan, chat, calculate, import, generate images or video, connect or run a plugin, or upload media. Submitting content to an AI feature authorizes the processing needed to return that result.

Uses: Generate the requested output, operate and safeguard features, troubleshoot failures, and comply with law. BrainBoost does not sell your learning content or use it to train foundation models. Providers may retain requests briefly for abuse monitoring under their policies. See openrouter.ai/privacy and the applicable model provider’s policy.

Stopping AI processing: Stop submitting content, uninstall the App, delete your account (Profile → Account → Delete Account), or email thebrainboost2025@gmail.com.

3b. Automated processing and AI accuracy

AI accuracy disclaimer. BrainBoost AI can make mistakes. Outputs are generated automatically and may be inaccurate, incomplete, or confidently wrong. They are for educational study assistance only—not legal, medical, mental-health, financial, or other professional advice—and are not used to make legally binding decisions about you.

  • Homework Scanner / OCR can misread handwriting, diagrams, faded ink, or low-quality photos; wrong reads produce wrong solutions.
  • Chat, tutor, and Learning Hub answers can contain errors even when phrased confidently.
  • Math solutions, quizzes, summaries, study plans, and calculator steps may include critical mistakes.
  • Image, media, or Seedance study-video generation may produce incorrect diagrams or inappropriate imagery despite filters.
  • AI Detector scores are estimates only—not definitive authorship findings for schools or employers.
  • Style & Tone / Humanizer tools do not guarantee originality, “undetectable” text, or academic honesty outcomes. They are not for cheating or misrepresenting authorship.
  • Verify important information with reliable sources, instructors, or a qualified professional before submitting graded work.

3c. Schools and FERPA

BrainBoost is a consumer study app, not a school or “educational agency or institution” under FERPA. We do not claim FERPA compliance as a school records system. Optional school/class labels are self-reported study context, not official education records maintained by your institution.

4. Third-party services

4c. Subprocessors (service vendors)

Depending on features you use, personal information may be processed by: Supabase; OpenRouter and its model partners; Google (Sign in, AdMob, AdSense, optional Google plugins); Apple (Sign in, App Store, App Tracking Transparency); Stripe and RevenueCat; Microsoft (Edge TTS); Composio; Netlify; and Expo. Each vendor’s privacy policy governs that vendor’s processing.

4a. Advertising

The free tier is ad-supported. Free users receive 20 flexible uses per day and may see native rewarded ads (watch an ad to earn +2 uses; maximum 10 rewarded ads per day), occasional native interstitials, and non-rewarded web display ads. Google AdMob provides native ads; Google AdSense provides web display ads. We request applicable Google consent before native ad requests and currently request non-personalized native and web ads. On iOS you may decline App Tracking Transparency. Web display ads never grant usage rewards. Premium subscribers do not see ads.

4b. Usage limits

Limits reset at midnight in your local timezone and are tracked by device and, when signed in, by account.

5. Sharing and disclosure

We do not sell personal information for money. We disclose data to service providers to operate the App; to Google for ads as described; when required by law; to protect against fraud or abuse; and in a merger or sale (users will be notified).

6. Your privacy rights

You may request access, correction, deletion, or a portable copy of eligible personal information by emailing thebrainboost2025@gmail.com. You may also delete your account in the App: Profile → Account → Delete Account. Control AI Memory: school and class labels live in Profile; signed-in users may manage or clear structured AI-memory preferences. BrainBoost does not keep a separate memory of chat transcripts, homework, grades, or attachments. We do not currently send marketing email; support, security, purchase, or account messages may still be sent.

Account deletion removes the cloud account and account-linked content targeted by the deletion flow. Limited transaction, entitlement, device-usage, fraud-prevention, security, and legal-compliance records may be retained where necessary. Local data remains until you uninstall the App or clear its data.

6a. California (CCPA / CPRA)

California residents may have rights to know, access, delete, correct, and obtain a copy of personal information, to opt out of “sale” or “sharing,” and to non-discriminatory treatment. We do not sell personal information for money. AdMob / AdSense disclosures may be considered “sharing” under California law when used for cross-context behavioral advertising. Decline App Tracking Transparency on iOS, use device or Google ad controls, or email thebrainboost2025@gmail.com with subject “California Privacy Request.” You may use an authorized agent if you provide written permission and we can verify both identities, except where the law lets us require you to use our process.

Categories of personal information we may collect, depending on how you use the Service: identifiers (email if you sign in; account/device/session IDs); commercial information (subscription and purchase-status); internet or electronic activity (feature-usage events that do not include homework or chat text); user content you submit (photos, files, prompts, voice for dictation); inferences or preferences you set (academic profile and AI-memory labels); and approximate technical data (app version, language, device type). We do not intentionally collect precise geolocation, government IDs, or biometric templates. We do not use sensitive personal information to infer characteristics about you for cross-context advertising.

California “Shine the Light” (Civil Code § 1798.83): we do not disclose personal information to third parties for those parties’ direct marketing. We have no actual knowledge of selling or sharing personal information of consumers under 16.

6b. EEA, UK, and Switzerland (GDPR / UK GDPR)

Legal bases include contract (providing the Service), consent (AI processing, optional sign-in, optional plugins), legitimate interests (security, abuse prevention, analytics), and legal obligations. You may access, rectify, erase, restrict, or port your data, object to certain processing including targeted advertising where applicable, and withdraw consent. We do not currently appoint a named Data Protection Officer; email thebrainboost2025@gmail.com. You may lodge a complaint with your local authority (for example the ICO in the UK).

6c. Other U.S. state privacy laws

Residents of states with comprehensive privacy laws may have similar rights to access, delete, correct, or opt out of sale, targeted advertising, or certain profiling. We do not sell personal information for money. Email thebrainboost2025@gmail.com with subject “State Privacy Request.”

7. Children’s privacy (COPPA)

Age 13+ requirement. The App is not directed to children under 13. By using BrainBoost, you represent that you are at least 13. We do not knowingly collect personal information from children under 13 without verifiable parental consent. We do not sell personal information of children. If we learn that an under-13 user provided personal information, we will restrict access and delete applicable data. We do not currently use a hard age-verification gate beyond this policy and related account controls. Parents should email thebrainboost2025@gmail.com immediately.

8. Data retention

9. International transfers

Your data may be processed in countries other than your own, including the United States. We rely on provider data-processing terms and transfer safeguards such as Standard Contractual Clauses where required, and other lawful mechanisms under applicable privacy law.

10. Cookies, localStorage, and tracking

On the web Service we use cookies and browser localStorage / sessionStorage. Mobile apps use on-device storage (including AsyncStorage), SDK identifiers, and authentication tokens.

Clearing cookies or site data does not delete cloud account records. Disabling essential storage may prevent sign-in or saved study materials from working.

Do Not Track / Global Privacy Control: We honor legally required opt-out signals where we can reasonably detect them, including Global Privacy Control (GPC) for “sale” or “sharing” / targeted advertising where applicable. Browser “Do Not Track” is not uniformly implemented across the industry; use device, browser, and Google ad controls as well. We currently request non-personalized ads.

11. Changes

We may update this policy. Significant changes will be noted by updating the effective date and, where required, by email or in-app notice or consent. Continued use after changes constitutes acceptance.
