Summary: Olodo is an offline-first educational active recall examination prep app and educator vetting portal built by Lifu Inc / Brain Squard Studio. We respect student privacy: we do not sell personal data, we do not run behavioral advertising, and all question drills work 100% offline once downloaded.
1. Information We Collect
We collect only the minimum information necessary to deliver offline-first study drills, active recall rescue assistance, and legitimate educator content vetting:
- Account & Identity: When you register or sign in via Google Sign-In or email, we collect your name and email address.
- Academic Profile: Your selected educational tier (Primary School, Junior Secondary, Senior Secondary, Tertiary, or National Examinations like WAEC/JAMB), institution/school name, department/faculty, class level, and academic period (Term or Semester).
- Study Progress & Mastery Scores: Rounds completed, question recall results, and exam pass status (such as achieving the 7/10 mastery gate). This information is stored locally on your device and synchronized with your authenticated profile.
- Billing & Entitlements: Purchase tokens, subscription receipts, and transaction identifiers confirming your Single Subject Pass or Full Term/Semester Pass processed securely by Google Play In-App Billing. We never collect or store debit card, credit card, or bank account credentials.
- Device Identifiers & Hardware Registry: An installation-scoped instance identifier and hardware device token stored in our database (
user_devices) solely to bind and validate your active single-device subscription or pass entitlement, prevent multi-device license abuse, and maintain session integrity. We do not use persistent hardware identifiers (like telephony IMEI or MAC address) for tracking or advertising.
2. How We Use Your Information
We use collected data solely to:
- Deliver bite-sized 10-question study sessions and progressive active recall typewriter clues.
- Ensure courses remain accessible 100% offline without recurring internet data usage.
- Verify academic passes and license durations (e.g. 180-day Term/Semester passes).
- Attribute revenue pools accurately to verified educators and curriculum authors via our Web Vetting Ledger.
- Prevent illicit distribution and protect educator intellectual property via unobtrusive on-screen student watermarks.
3. Childrenâs Privacy (Primary & Secondary Education)
Because Olodo serves learners across Primary (Basic 1â6) and Secondary schools, protecting young learners is paramount:
- We comply with global child protection standards, including COPPA (Childrenâs Online Privacy Protection Act) and Nigerian data privacy regulations (NDPR).
- In accordance with Google Play Families Policy and COPPA, device identifiers collected for younger learners are strictly scoped to technical app functionality, subscription authorization, and session security, and are never used for profiling, behavioral analysis, or advertising.
- We do not collect personal phone numbers, physical addresses, or location data from students.
- The application contains zero social media feeds, third-party behavioral tracking, or unmoderated chat channels between users.
- Parents and guardians may request review or deletion of their childâs profile at any time by contacting our support team.
4. Offline Storage & Anti-Piracy Watermarking
To support Nigerian students studying with limited or intermittent internet connectivity, Olodo operates with an offline-first architecture:
- Downloaded course packs are cached in encrypted local storage on your device.
- During active study and quiz sessions, an unobtrusive watermark displaying your registered student identifier is rendered to safeguard verified educator materials from illegal external distribution.
5. Third-Party Services & Security
We utilize industry-leading infrastructure partners who adhere to rigorous security standards:
- Google Play In-App Billing: Handles all in-app subscription and pass payments with bank-grade encryption.
- Google Firebase (Authentication & Cloud Firestore): Manages secure user authentication, vetted question repository distribution, and database encryption in transit and at rest.
6. Data Retention & Account Deletion
We retain your academic progress for as long as your account remains active. You maintain full control over your personal data:
- You may clear your downloaded course packs at any time directly inside the mobile app drawer under Offline Storage.
- To request permanent account and data deletion, tap Request Account Deletion in the mobile app side drawer or under the Account & Data Privacy section in Settings, visit our public Account & Data Deletion Portal, or email our support team at lifujosephlifu@gmail.com with the subject line "Account Deletion Request". We process complete data removal within 7 business days.
7. Changes to This Privacy Policy
We may update this Privacy Policy occasionally to reflect platform improvements or regulatory compliance. Any revisions will be published on this page with an updated Effective Date.
