Privacy Policy

Last updated: October 11, 2026

The short version: your content never leaves your phone. Privaku apps process everything on your device. We have no servers that receive your photos, text or voice, and we don't track you for ads.

Who we are

Privaku (プリバク) is an independent software studio based in Tokyo, Japan, building privacy-first mobile apps. This policy covers this website (privaku.com) and Privaku apps, including Ask My Photos and AI Action App.

Data we collect

We never collect your content (photos, text, voice or files). To keep the apps stable, they use Google Firebase to send crash reports and basic, anonymous app usage and performance data. This data never includes your content, and you can turn it off in each app's Settings. We do not sell personal data, and we do not require an account to use our apps.

On-device processing

All AI features run locally on your device. Your photos, text, voice and other content are processed on your phone and are never uploaded to us or to any third-party AI service.

Network use

Our apps use the network to download AI model files and app resources, and to send the crash and usage data described above. None of these requests contain your content. Purchases, if any, are handled by the app store you download from, under its own privacy policy; we receive no payment details.

No ad tracking

• No advertising or advertising identifiers
• No cookies or trackers on this website
• No third-party fonts, scripts or embeds on this website

Our website host may keep standard, short-lived server logs (such as IP address and pages requested) for security and reliability. We do not use these logs to identify or profile you.

Emailing us

If you email us, for example to join the waitlist, we receive your email address and message. We use it only to reply or to send the launch notice you asked for, and we delete it on request.

Children

We do not knowingly collect any data from anyone, including children.

Changes

If this policy changes, we'll update this page and the date above. Our core promise will not change: no cloud, ever.
