Privacy Policy

Last updated: 25 Nov 2025

Welcome to “Zivo AR Drawing” (“the App”). This Policy explains how Nanjing Heyback Technology Co., Ltd. (“Company”, “we”) collects, uses, shares, and protects information when you use the App. Because Zivo does not provide account registration, all data is linked only to device-level identifiers or randomly generated session IDs.

II. Data We Collect

We do not ask you to create an account, and we do not upload your drawings or live camera feed to our servers. We may process the following categories of information in order to deliver AR drawing features, subscriptions, and advertising:

  1. Device & App Diagnostics (Firebase Analytics)
    Device model, OS version, language, region, time zone, app version, first launch time, coarse location inferred from IP, engagement events (e.g. “created AR board”, “exported timelapse”).
    Purpose: product analytics, crash reproduction, feature prioritisation.

  2. Crash & Performance Logs (Firebase Crashlytics)
    Stack traces, device status at crash, anonymised installation ID. These logs help us stabilise AR rendering and camera pipeline.

  3. Subscription & Purchase Metadata (RevenueCat)
    Store country, product identifier, receipt / purchase token, renewable status, pricing, promotional offers. No full payment instrument data reaches us.

  4. Advertising & Attribution Data

  5. Camera & Photo Library Permissions
    We use the rear camera, LiDAR/ARKit/ARCore data, and optionally your photo library to overlay drawing guides. Frames and photos are processed on-device and are not uploaded to our servers; only permission status is logged for diagnostics.

  6. Support Communications
    If you email us, we receive the information you provide (email, attachments, device screenshot). We use it solely to resolve your request.

You may withdraw consent for advertising tracking at any time in iOS Settings › Privacy › Tracking or Android Settings › Google › Ads. This will not affect processing performed before the withdrawal.


IV. Permissions & Sensors

Permission Reason of Use Storage
Camera / ARKit / ARCore Render live AR brushes and anchors; capture reference planes Frames stay on device; we only log permission status
Photo Library / Storage Import pictures as tracing layers Imported files stay local; metadata is not uploaded
Network Download brush packs, sync subscriptions, load ads Minimal telemetry (as listed above)
App Tracking Transparency / Advertising ID Deliver personalised ads when you opt in Identifier is shared with ad partners per their DPAs

We currently do not access motion sensors beyond what ARKit/ARCore requires; if future versions do, we will update this Policy first.


V. Data Retention

Data Type Retention Policy
Firebase Analytics events 26 months (default Google retention)
Crashlytics logs 90 days, automatically purged by Google
RevenueCat subscription metadata Retained during active entitlement + 3 years for tax/audit
Ad impression / attribution data Up to 24 months depending on network requirements
Support tickets Deleted within 24 months of resolution unless law requires longer

Uninstalling the App removes locally cached brushes, preferences, and any downloaded scenes.


VI. Storage & Cross-border Transfers

Operational services run on Alibaba Cloud (Singapore region). Telemetry may also be stored by Google (United States, EU), RevenueCat (United States), Meta (global infrastructure), and Apple (United States/EU). We rely on Standard Contractual Clauses (SCC 2021/914/EU) or equivalent safeguards provided by each processor.
