What Signata records

While armed, Signata records physical events on the Mac it runs on: wake and sleep, screen lock and unlock, USB attach and detach, volume mount and unmount, display changes, and audio output changes. Each entry carries a timestamp, an event kind, a summary, and local context such as the machine name, the user name, and where available the battery level, the network name, and the reason the Mac woke.

With Evidence Mode enabled — off by default — Signata may also create a camera snapshot or a desktop screenshot after a configured event. Screenshots can contain whatever was on your display.

What never leaves your Mac

Stated affirmatively, because "we do not sell your data" is a low bar:

Event history	Stays in the app container. Never transmitted.
Evidence files	Stay in the app container. Never transmitted, never attached to an alert.
Location	Not collected. No location code exists in the app.
Usage and analytics	Not collected. There is nothing to collect it with.
Credentials	Stored in the macOS Keychain, never in preferences or logs.

The one thing that can leave

If — and only if — you enable an alert channel and supply your own credentials, Signata sends an event kind, a local timestamp and a summary to that channel. Two are supported:

• Telegram, through a bot you create, to a chat you choose.
• An HTTPS webhook, to any endpoint you nominate.

Both are third-party services chosen and configured by you. Whatever you send them is subject to their terms, not ours, and StacknScope Inc. has no visibility into either. Signata does not proxy alerts through any infrastructure we run, because we don't run any.

Where your data lives

Inside Signata's sandbox container on your Mac:

~/Library/Containers/com.stacknscope.Signata/Data/Library/Application Support/Signata/

You can read it with any text editor — the event log is JSON Lines, and the format is published. Evidence files are ordinary images in a dated folder.

Retention and deletion

You control it. Evidence has a keep-days window and a total storage cap, both configurable, applied automatically. Nothing has a server-side copy, so deleting a file deletes it — there is no second copy to also delete.

Uninstalling Signata and removing its container removes everything. Because there is no account, there is nothing to close and nothing to request from us.

The camera and the screen

Evidence Mode is off by default, each capture type has its own opt-in, and each requires the corresponding macOS permission. Beyond that, Signata operates under constraints it will not relax:

• Capture is never triggered remotely — only by an event on the machine while you have armed it.
• Hidden operation and capture are mutually exclusive. Signata will not offer a concealed mode that also photographs.
• The macOS camera indicator is never suppressed or worked around.

Denying either permission is a supported state. Events keep recording and the app degrades quietly rather than nagging.

Purchases

Payment is handled by our payment processor. StacknScope Inc. receives the information needed to issue a licence and honour a refund — an email address and a transaction reference — and never sees your full card details. Signata itself does not transmit purchase information; licence validation happens without reporting your usage.

This website

signata.app is static files. No cookies, no analytics, no tracking pixels, no embedded third-party scripts, no fonts fetched from anyone else's server. Our host records standard request logs for delivery and abuse prevention; we do not build profiles from them.

The tamper-evidence demo on the home page runs entirely in your browser. Nothing it computes is sent anywhere.

Launch notifications

The home page has one form, and it is the only place this site asks you for anything. If you enter an address there, here is everything that happens to it.

We store the address, the time you submitted it, the time you confirmed it, and a random token. That is the whole record. We do not store your IP address, your browser, or the page you came from. It lives in a Cloudflare D1 database in the United States, and it is the only database this project has.

Nothing is sent to an address that has not been confirmed. Submitting the form gets you one message asking you to confirm, and if you never open that link, you never hear from us again. That is deliberate: it means someone else typing your address into this form cannot sign you up for anything.

A confirmed address receives one email, on the day Signata is released. There is no newsletter and no second message. Every email we send carries a link that deletes your address — deletes, not marks inactive — and the same link is available any time you want it. Once the launch announcement has gone out, the entire list is deleted.

Delivery is handled by Resend, who process the address on our behalf in order to send the message. They are the only third party that sees it. We do not sell, rent, share or otherwise hand your address to anyone, and it is not connected to any purchase you may later make.

Write to support@stacknscope.com at any time to see what we hold for your address or to have it removed, and we will do it without asking why.

Children

Signata is a utility for Mac owners and is not directed at children. The app collects nothing from anyone. The launch notification list is the one place this project holds a personal detail at all, and we do not knowingly accept an address from a child.

Changes

Material changes will be published here with a new effective date before they take effect, and the in-app policy will match. If a future version of Signata ever collects something this page says it doesn't, that page changes first.
