# Privaku: details for AI agents > Index: https://privaku.com/llms.txt. Privaku is a Tokyo studio (made in Japan) building privacy-first apps with AI that runs on your own device. ## Privaku Photos (iPhone) - URL: https://privaku.com/ask-my-photos/ · App Store: https://apps.apple.com/app/id6821608477 - Price: free, and it always will be. No ads, no subscriptions, no in-app purchases. No account. - Requires: iPhone with iOS 18 or later. - Features: review exact duplicates and similar photos side by side; clean up safely (nothing is deleted until you confirm in the iOS system dialog, and deleted photos go to Recently Deleted); Emergency Docs shows photos of your passport, residence card, insurance card or boarding pass in one tap, grouped by type. - Privacy: photo analysis and cleanup run on the iPhone; photos never leave it. The app checks one setting online at launch (a remote configuration value, using a random installation ID); no photos or personal data are sent. It works in airplane mode. - Photo access: full or limited access; change it in iOS Settings > Privacy & Security > Photos > Privaku Photos. - Recovering a deleted photo: Photos app > Albums > Recently Deleted > select > Recover. - Bug reports: support@privaku.com with iPhone model, iOS version, app version and steps. ## Agent Shield (Mac, beta) - URL: https://privaku.com/agent-shield/ · Download: https://privaku.com/download/agent-shield.dmg (version 0.1.0, macOS 13 Ventura or later, free) - What it does: checks every file read, shell command and tool call from supported AI coding agents against your rules before it runs. Blocks reads of .env files, SSH keys, cloud credentials and keychains; blocks or holds dangerous shell commands; checks calls to unapproved MCP servers and masks secrets in replies; stops agent uploads to hosts you haven't allowed. - Limits: it works at the tool-call layer of supported agents and doesn't yet stop a program that opens its own network connection directly. - Privacy: your code, files and prompts are not uploaded. No telemetry, no account in the app. - Licence: the core (policy engine, rules format, default rules, agent adapters) is source-available under PolyForm Shield 1.0.0. - Verify: each release publishes a SHA-256 hash (shasum -a 256 ~/Downloads/Agent-Shield-0.1.0.dmg). - Security issues: security@privaku.com ## Action AI (iPhone) - Coming soon.
