The Tatammi app has no analytics, no telemetry and no account. It does not track how you use it. No server receives anything about how you use the app, because no such server exists. Tatammi does contact our update feed, our payment provider to check your licence, and, only if you agree to it, our crash endpoint after a crash. All three are listed in full below.
This website counts visits, so we know whether anyone is finding it. That counting is aggregate and cookieless: no cookies, no fingerprinting, no profile, nothing that identifies you, and nothing shared with advertisers or followed across other sites. It applies to these pages only, never to the app.
Everything Tatammi knows about your workspaces stays on your Mac, in your own user preferences:
To arrange windows, Tatammi reads window positions, sizes and titles through macOS's Accessibility and window-management APIs. That information is used in the moment to lay out your screen and is never transmitted, stored remotely, or written anywhere outside your own preferences.
| When | What is sent |
|---|---|
| Checking for updates Automatically once a day, or when you choose “Check for Updates…” |
Tatammi requests https://tatammi.com/appcast.xml. As with any web request, our host receives your IP address, the app version and basic system information supplied by macOS. This is used only to serve the file and is not combined with anything else or used to identify you. Automatic checks can be turned off in Settings. |
| Checking your licence When you activate, and occasionally afterwards |
Tatammi asks api.polar.sh whether your licence key is still valid, sending the key itself and a label for this Mac (its computer name). Polar is our merchant of record and handles the purchase; their privacy policy covers what they hold. Nothing about how you use the app is sent, and if the check cannot be made Tatammi keeps working. See below. |
| Sending a crash report Only if you agreed when asked, and only after a crash |
The first time you run Tatammi it asks whether it may send crash reports. If you said yes, a report of the crash is sent when the app next starts: what went wrong, and your macOS version. It never includes your desktop names, your window titles, what you were working on, or anything about how you use the app. Change your mind at any time in Settings. |
| Reporting a problem Only when you choose “Report a Problem…” |
Nothing is sent by Tatammi. It opens a draft in your own mail app, prefilled with your app version, macOS version, whether permissions are granted, and how many displays and desktops you have. You can see and edit all of it, and nothing is sent unless you press send. |
That is the complete list. Tatammi makes no other network connections.
What activation sends, and what it does not. Checking a licence sends your key and a label for the Mac you are on, meaning its computer name, so you can tell your machines apart when you manage them. It does not send your documents, your window layout, your desktop names, or anything about how you use the app. Polar, our payment provider, records that a licence was activated on a machine; that is what makes the three-Mac limit and releasing a seat possible.
Losing your connection does not lose you the app. Tatammi remembers its last successful check and keeps working for a fortnight without one, so a flight, a bad hotel network or an outage at our end costs you nothing. You never need a connection to use Tatammi, only occasionally, to confirm the licence is still yours.
You do not have to take our word for any of this. Point a network monitor such as Little Snitch or LuLu at Tatammi and watch: apart from the update check, the licence check, and a crash report you have agreed to, it does not talk to anything.
Purchases are handled by our payments provider, who acts as merchant of record and processes your payment details and the tax information required to complete the sale. We receive your email address and licence details in order to deliver your licence and provide support. We never see your card details. Your licence key is stored on your Mac.
If you email us, we keep that correspondence so we can help you and follow up on the issue. We don't add you to a mailing list, and we don't pass your address to anyone else.
Since we hold almost nothing, there is little to request, but you can ask what we have, ask us to correct or delete it, or ask for a copy, by emailing hello@tatammi.com. Purchase records may need to be kept where tax law requires it.
Tatammi isn't directed at children under 13, and we don't knowingly collect anything from them.
If this policy changes, the date above changes with it, and material changes will be noted in the app's release notes.
