Operator: NodajiFi Labs · Applies to: the NodajiFi app (part of the NodajiFi ecosystem) · Effective date: July 1, 2026 · Last updated: July 1, 2026
This app-scoped policy supplements the ecosystem-wide NodajiFi Privacy Policy. Where the two differ for NodajiFi, this page prevails.
Introduction
NodajiFi Labs ("we," "us") respects the privacy of users worldwide and honors the standards of the GDPR and CCPA as well as the data-protection laws of your country of residence.
Core principle — you own your data. We do not record personal data on any blockchain, GEM has no cash value so we collect no financial or payment-related sensitive data, and we do not collect your real name or government-issued ID number.
1. Common account data
| Category | Items | Purpose |
|---|---|---|
| Account / authentication | Email address, phone number, passwordless login credentials (magic link / OTP) | Identification, authentication, account recovery, security |
| Profile (optional) | Nickname, avatar (no real name required) | Personalization, display |
| Age verification | "Aged 16 or older" result derived from date of birth at sign-up (raw date of birth is discarded) | Eligibility, child protection |
| Device / access | Device identifier, OS / app version, IP address, access logs, push token | Operation, security, notifications |
2. NodajiFi-specific data & permissions
| Category | Items | Purpose |
|---|---|---|
| Camera / AR (hands-on labs) | Real-time camera frames during practice sessions | On-device landmark/pose analysis for coaching and scoring. Raw practice video is processed on your device and is not uploaded. |
| Learning records | Quiz/exam/course/lab progress and scores, GEM earn/spend history | Service delivery, reward calculation, certificates |
| Optional media | Profile avatar you choose to set | Display |
Camera honesty. Hands-on analysis runs on your device; raw video does not leave your phone. Certificates anchor only cryptographic hashes — never personal data — and deleting your account destroys the off-chain record that links them to you.
3. How we use information
- Account management: identification, authentication, recovery, abuse prevention
- Service delivery: the NodajiFi features above, GEM earn/spend
- Service improvement: pseudonymized / anonymized usage analysis
- Notices: capped at 1–2 push notifications per day; you control frequency, timing, and type
- Legal compliance and dispute handling
4. Retention and deletion
We delete personal data without delay once its purpose is fulfilled, keeping only what applicable law requires for its required period. Account deletion is actually possible by design — see Delete Your Account. Unused GEM is forfeited on deletion; since GEM is not redeemable for cash, no settlement occurs.
5. Sharing and sub-processors
We do not sell personal data and do not share it with third parties except with your prior explicit consent or under lawful process. Core sub-processors: Google Firebase (authentication, database, push, analytics) and email/SMS delivery providers (passwordless sign-in). Data sharing between ecosystem apps does not operate without your explicit opt-in.
6. Protection of children (ages 16+)
The service is provided only to users aged 16 or older. At sign-up we take a date of birth, keep only the "16+" result, and discard the raw date. If we learn a user is under 16, we delete the account and its data without delay.
7. Your rights
You may request access, rectification, deletion, portability, restriction of processing, and withdrawal of consent — in-app via "NodajiFi Labs > Privacy" or by email to support@nodajifilabs.com. You may also lodge a complaint with your local data-protection authority.
8. Security
TLS encryption in transit, encrypted storage of sensitive data, access controls, server-authoritative abuse prevention, and no on-chain personal data by design.

We give in-app notice at least 7 days before changes take effect (at least 30 days for material changes adverse to users).
