This Privacy Policy explains how Walyro ("we", "us", "our") handles information when you use the Walyro macOS application ("App") and our website. The App is distributed via the Mac App Store and is designed to work primarily offline.

1) Key points

Walyro works primarily offline. Your wallpapers, library, and settings are stored locally on your Mac.
No accounts. We do not run user accounts, and we do not operate servers that store your videos or your wallpaper library.
No ads. Minimal app analytics. Walyro does not use advertising inside the macOS app, and we do not sell personal information. The App does use limited product analytics to understand feature usage and improve reliability.
The website uses analytics and campaign attribution. We use website analytics to understand visits and tagged outbound links to measure CTA performance.
Product analytics and crash reporting are on by default. The App sends anonymous product analytics to PostHog and anonymous crash diagnostics to Sentry to help us improve features and fix stability issues. You can turn either off at any time under Settings > General.
Analytics are anonymous. They use an anonymous, resettable per-install identifier — not your name, email, or Apple ID — and we do not build server-side person profiles.

2) Information we process

A) Data stored on your device (local)

Walyro processes and stores the following locally on your Mac to provide core features:

User-added wallpaper files (videos/images) you choose to add.
Pre-installed wallpapers shipped with the App.
Library data & settings, such as:
- per-display wallpaper selection,
- playback settings,
- app preferences and UI state.

This data is not uploaded to us.

B) Product analytics

By default, the App sends limited product analytics through PostHog to help us understand feature usage, onboarding flow, and stability trends. You can turn this off at any time in the App under Settings > General. We design this analytics stream to be low-profile and focused on aggregated product learning rather than advertising: there is no autocapture and no screen tracking, and we send only a small, pre-defined set of explicit product events with a limited set of properties.

This may include:

app version and basic device/software context such as macOS version,
anonymous feature usage events such as onboarding completion or wallpaper setup actions,
high-level interaction and reliability signals that help us improve the product.

These events are associated with an anonymous, per-install identifier rather than with your name, email, or Apple ID. You can reset this identifier at any time in the App settings, and we do not build server-side person profiles that link this data to an identified individual.

We do not use this analytics data for advertising, we do not sell personal information, and you can disable app analytics at any time under Settings > General. PostHog processes this data as our service provider; see the PostHog Privacy Policy.

C) Diagnostic data (crash reporting)

By default, the App sends crash and error diagnostics to Sentry to help us understand and fix crashes and stability issues. You can turn crash reporting off at any time in the App under Settings > General. This may include:

crash stack traces and error messages,
app version and basic device/software information (e.g., macOS version, device model, and memory usage),
timestamps and diagnostic context related to the crash.

Crash reports are not tied to your name, email, or Apple ID. We do not use Sentry data for advertising, and we do not sell this information. Sentry processes this data as our service provider; see the Sentry Privacy Policy.

If you turn off crash reporting under Settings > General, Walyro stops sending crash/diagnostic reports to Sentry.

D) Website analytics and outbound link attribution

When you visit our website, we may collect website usage information through Google Analytics, such as page views, referrers, approximate device and browser details, and interactions with key calls to action.

We also attach campaign parameters (such as UTM tags) to outbound links for destinations like our waitlist form, social profiles, and future App Store pages so we can understand which placements drive interest.

E) Information you provide to us

If you contact us (e.g., by email), we will receive the information you share such as your email address and the content of your message.

F) What we don't collect

To be clear about the limits of the above, Walyro does not:

require an account, login, or Apple ID sign-in to use the App,
collect your name or email address, except when you contact us directly (see section E),
upload, read, or collect the names, file paths, or contents of your wallpaper videos, which stay on your Mac,
collect precise geolocation.

3) How we use information

We use information to:

operate the App and its features on your device,
measure aggregated product usage and improve onboarding, feature quality, and reliability,
measure website traffic and outbound CTA performance,
provide support and respond to your requests,
improve reliability and fix issues (via Sentry crash diagnostics, which you can turn off).

Legal bases for processing (EEA/UK)

If you are in the European Economic Area or the United Kingdom, we rely on the following legal bases under the GDPR / UK GDPR for the limited personal data we process:

Legitimate interests — for limited, anonymous product analytics and crash diagnostics used to understand feature usage, improve reliability, and keep the App stable, weighed against your interests and rights (you can turn both off in the App settings at any time).
Consent — where consent is required for a specific processing activity or jurisdiction; where we rely on consent, you can withdraw it at any time by turning off the relevant setting.
Performance of a contract — to provide the App and the features you request.
Legal obligations — where we must process information to comply with applicable law.

4) How we share information

We share information only in these limited cases:

Service provider (PostHog), for limited in-app product analytics.
Service provider (Sentry), for crash/diagnostic reporting unless you turn it off.
Service provider (Google Analytics), for website analytics and reporting.
Service provider (Youform), if you choose to join our waitlist through the hosted form.
Legal reasons, if required to comply with applicable law or to protect rights, safety, and security.
Business transfer, if we are involved in a merger, acquisition, or asset sale (where required, we will provide notice).

We do not sell personal information.

International data transfers

Our service providers (such as PostHog, Sentry, and Google Analytics) may process information on servers located outside your country, including outside the EEA and the UK. Where personal data is transferred internationally, we rely on appropriate safeguards, such as the European Commission's Standard Contractual Clauses or a relevant adequacy decision, where these apply.

5) Data retention

Local wallpapers, library, and settings: remain on your Mac until you delete them or uninstall the App.
In-app product analytics: retained according to our PostHog project settings for product analysis and trend reporting.
Website analytics data: retained according to our Google Analytics settings.
Sentry diagnostic data (if enabled): retained for a limited period as configured in our Sentry project settings and as needed for troubleshooting.
Support communications: retained as long as reasonably necessary to address your request.

6) Security

We apply reasonable safeguards appropriate to the nature of the data. No method of storage or transmission is completely secure, but we aim to minimize collection, keep app analytics limited in scope, and let you turn off app analytics and crash diagnostics at any time.

7) Your choices and privacy rights

You can:

disable app analytics at any time under Settings > General,
enable or disable diagnostic/crash reporting at any time under Settings > General,
reset the anonymous per-install analytics identifier in the App settings,
remove wallpapers and reset your library from within the App,
uninstall the App to remove local data (subject to macOS behavior),
enable or disable launch at login ("Login Item") in macOS settings (this does not share your personal data with us).

To request deletion of support communications, contact us (see section 10).

Depending on where you live (for example, the EEA, the UK, or California), you may also have rights to:

access the personal data we hold about you,
request correction or deletion of your personal data,
object to, or request restriction of, certain processing,
receive a copy of your data in a portable format,
withdraw consent where our processing is based on consent, and
lodge a complaint with your local data protection authority.

Because Walyro has no user accounts and our in-app analytics and crash data are anonymous, we often cannot link this information to a specific person, and in those cases we may be unable to identify your data to action a request. Where we can, we will respond to verified requests as required by law. To make a request, contact us (see section 10). If you are in the EEA or the UK, you may also lodge a complaint with your local supervisory authority (in Cyprus, the Office of the Commissioner for Personal Data Protection).

8) Children's privacy

Walyro is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from children.

9) Changes to this policy

We may update this Privacy Policy from time to time. We will update the "Last updated" date and provide additional notice if required.

10) Contact
