M · Privacy

Last updated 9 November 2026

M ("M - Your line to your agent" on the App Store) is an iPhone app by Stratara Ltd (company no. 517197182, Israel; "Stratara", "we") that lets your AI agent on your Mac message you on your phone, and get your answers back. Your messages, answers, pictures, signals and morning paper are sealed before they leave your phone or your Mac: by the app on your phone, and on your Mac by the script your agent builds from our specification. Only your phone and your Mac hold the keys to open them. Stratara and Apple carry the sealed messages but can't read them.

What our relay keeps

• For each pairing of your phone with your Mac: a random identifier, the two public keys (they can check signatures and seal messages, but can't open them) with the check that ties each one to your pairing, and the push addresses Apple gives your phone.
• Sealed messages until they're collected, for a week at most.
• The size and time of each item until it's collected, and a count of items each day, to keep within the limits.
• Apple's signed record of your trial or subscription, to check that it's active.
• For up to a day, a scrambled form of the internet address that starts or claims a pairing, to stop abuse. The secret that scrambles it changes every day.
• Reminders for your agent (M's suggestions, such as the morning paper and Plan my day, the reminders you write, and those your agent sets itself): up to 64 sealed items, at most eight days ahead, each with the time it's due and which kind it is, deleted when it's sent or set aside. For M's suggestions, for at most an hour: when your Mac last checked in and when the line was last used, so a suggestion goes only to a line that's open and quiet.

We keep it until you unpair, which deletes it all at once, or until 90 days after the pairing was last used or your subscription ended.

What we don't do

We don't sell anything about you, show ads, track you across apps or websites, or use anything you send to train AI models. You don't need an account, an email address or a password.

Others involved

• Apple delivers notifications to your phone, sealed, and handles your subscription and payment under Apple's own terms.
• Cloudflare hosts our relay and handles each request, your internet address included, under its own privacy policy.
• Your agent. Once your agent opens a message from your phone, it handles it like anything else you tell it, and so does the company that runs it (Anthropic, for Claude Code), under that company's terms. The setup text you paste into your agent goes to it the same way.

Your choices

Each signal (where you are, Focus, busy or free, how you're moving, battery, when you last answered) is off until you turn it on in Settings, and you can turn it off at any time. M's suggestions (the morning paper and Plan my day) are on until you turn them off in Settings, and each reminder you write has its own switch. Unpair in the app to delete everything our relay holds for that pairing. You can ask us what we hold, to correct it or to delete it: write to info (at) stratara (dot) ai.

Children

M isn't for anyone under 18.

Do Not Track

M doesn't track you across apps or websites, so a Do Not Track signal changes nothing.
