Privacy Policy
ADHZ processes personal information in the Nyanbyte app and website as described below.
Effective date: 2026-10-18
1. Information and purposes
Videos, thumbnails, filenames, photo-library identifiers and capture locations stay on your device. Other information processed when you use the service is listed below.
| Category | Information | Purpose |
|---|---|---|
| On-device processing | Permitted videos, thumbnails, filenames, dates, duration, size, resolution, task/error history and settings | Analysis, compression, comparison, saving and recovery |
| Purchases | Installation ID, app/device/OS details, product/receipt/transaction IDs and purchase/subscription/refund status | Access verification, restoration and purchase support |
| Optional analytics | Installation/session IDs, app/OS/language, feature and purchase activity, processing counts, time and space saved | Feature and purchase-flow improvements |
| Optional diagnostics | Error types, codes and stacks, app/device/OS details and installation ID | Error investigation and reliability |
| Support | Email and any name, message or attachments provided | Replies and dispute resolution |
| Website access | IP, request address/time, browser and connection details | Website delivery, security and troubleshooting |
| Website statistics | Pages, referral sources, browsers and loading performance | Traffic and performance improvements |
2. Collection and your choices
Manage photo permission in device settings. Local processing and purchase verification/restoration operate as needed for the service. RevenueCat checks access at app start, including before purchase.
Usage analytics and error diagnostics are off by default. Turning on optional usage and error sharing in Settings enables the transfers to PostHog and Sentry described below. Leaving it off does not affect paid access.
Turning sharing off stops new transfers; pre-consent activity is not sent. Section 6 explains withdrawal and deletion of existing data.
3. Processors and international transfers
Purchase processing relies on overseas processing/storage needed to perform the service contract; optional analytics and diagnostics rely on separate consent. Listed data is transferred over encrypted connections during the relevant activity. Videos are not transferred.
| Recipient and contact | Country, transferred data, purpose and timing | Retention and use |
|---|---|---|
| RevenueCat, Inc. · compliance@revenuecat.com | United States · section 1 purchase data · access verification/restoration at app start, purchase, restoration and store changes | As needed for access verification/restoration and statutory retention |
| PostHog, Inc. · privacy@posthog.com | United States · section 1 analytics · feature/purchase-flow analysis during app use after consent | Until the purpose is fulfilled or withdrawal is received, whichever is earlier |
| Functional Software, Inc. (Sentry) · compliance@sentry.io | United States · section 1 error data · investigation when errors occur after consent | Until the purpose is fulfilled or withdrawal is received, whichever is earlier |
| Cloudflare, Inc. · privacyquestions@cloudflare.com | United States and other countries · website access/statistics and email · delivery, security, statistics and email forwarding on visits or email sending | As needed for website/email services and statutory retention. Traffic data is aggregated/sampled after seven days and retained as needed for statistics. |
| Google LLC (Gmail) · policies.google.com/privacy | United States and other countries · support email · receipt, reply and storage when sent | As needed for enquiries, disputes and statutory retention |
4. Third parties and refusing international processing
We do not sell personal information. Apple and Google handle store accounts and payments under their own policies. Other disclosures require consent or a legal basis.
You may refuse optional transfers. Refusing transfers needed for purchases may limit verification/restoration. Contact us by phone or post if you do not want support email processed overseas.
5. Retention and deletion
We delete data without delay when its purpose or retention period ends or consent is validly withdrawn, except for legally required records. We request provider deletion; backups awaiting deletion are restricted from use. Electronic records are irrecoverably deleted and paper records shredded.
- Local records/settings remain until cleared or uninstalled. Unsaved results are cleared after 24 hours at the next cleanup only when another usable copy exists.
- Uninstalling does not cancel store subscriptions or erase external records. Statutory records below are retained separately.
| Statutory records · only where applicable | Period |
|---|---|
| Contracts, withdrawal, payment and supply records | 5 years |
| Consumer complaints and disputes | 3 years |
| Display and advertising records | 6 months |
6. Your rights
You or your legal representative may request access, correction, deletion, restriction or consent withdrawal through app support, email, phone or post.
We act without delay after minimal identity checks and explain any legal restrictions. Manage local data in app/device settings.
Where consent is required to process a minor’s personal information, the applicable legal representative consent requirements apply.
7. Automatic collection and safeguards
Cloudflare Web Analytics collects website traffic/performance statistics without analytics cookies or fingerprinting. We do not link them to app installation/purchase IDs. Connection IPs may be processed separately for delivery and security.
The app does not use advertising IDs, cross-app advertising tracking, screen recording or session replay. Safeguards include encrypted connections, access restrictions, analytics/error data filtering and processor oversight.
