Privacy Policy
Last updated: 22 August 2026
The short version. Atlas runs entirely on your own computer. We do not operate a server that stores your data, and we never receive the documents you file. We could not access them if we wanted to.
Information leaves your device only when you choose to send it, and there is exactly one such feature: optional AI answers, which are off by default and ask for your approval every single time.
1. Who we are
Atlas is a Windows desktop application published by SyphonDigital, a sole trader registered in Australia. In this policy, "we", "us" and "our" mean SyphonDigital; "you" means the person using Atlas.

2. The most important thing to understand
Atlas is local-first software, not a cloud service. When you import a document it is copied, read, indexed and stored on your own computer, inside your Windows user profile. There is no SyphonDigital account, no sign-up, no upload step, and no copy of your data on our systems.
This is not a policy promise that could quietly change with a server-side deployment. It is how the software is built: Atlas has no code that transmits your documents anywhere, apart from the optional AI feature described in section 5.
3. What we collect
Nothing. Atlas contains no analytics, no telemetry, no crash reporting, no usage statistics, no licence check and no "phone home" of any kind. It does not check for updates. We do not know that you installed it, when you run it, or what you put in it.
If you email us for support, we receive whatever you choose to put in that email, and we use it only to answer you.
4. What stays on your computer
All of it. Specifically, inside your Windows user profile Atlas keeps:
- a vault holding a copy of every file you import;
- a database holding extracted text, dates, amounts and identifiers, your categories, tags, reminders, and the relationships between the things in your life;
- a search index built from that text;
- a log file recording what the app did, for troubleshooting.
Back that one folder up and you have backed up everything. Delete it and Atlas has nothing.
5. The one feature that sends anything out
Atlas can optionally send a question to Anthropic's Claude API to answer open-ended questions its own local engine cannot. This feature is off by default and stays off until you deliberately enable it, agree to a consent screen and enter your own Anthropic API key.
When it is on, every single request:
- shows you a dialog naming each document whose text would be sent and the exact character count, before anything is transmitted;
- sends only excerpts, capped in the code at six documents and 1,500 characters each. Whole documents and files are never transmitted;
- requires you to press Send. There is no "remember my choice".
Those excerpts go to Anthropic under your API key and are governed by Anthropic's terms and privacy policy, not ours. They never pass through any SyphonDigital system. Turning the feature off, or removing your key, ends it completely.
6. Your API key
If you provide an Anthropic API key it is encrypted using the operating system's own protection (Windows DPAPI, via Electron safeStorage) and stored in a file outside the Atlas database, deliberately, so that it is never included in a backup or an export you might share. We never see it.
7. Reminders and the calendar file
Atlas can write your reminders to a calendar (.ics) file at a location you choose. That is an ordinary file on your disk. If you place it in a synced folder such as OneDrive or Dropbox so your phone can subscribe to it, the syncing is done by that service under its terms, and the file will contain your reminder titles and dates. Where to put it is entirely your choice; Atlas does no syncing of its own.
8. Children
Atlas is not directed at children, and we knowingly collect no data from anyone, of any age.
9. Your rights
Privacy rights such as access, correction and erasure are rights against whoever holds your data. For Atlas that is you: the data is on your machine, and the app lets you edit, export, permanently delete or encrypt any of it without asking us. We hold nothing to give you, correct or delete, so there is nothing to request from us.
If you have emailed us for support and want that correspondence deleted, ask and we will delete it.
10. If we are ever compelled to hand over data
We cannot. We do not hold your documents, so there is nothing for us to produce in response to any request or order. If you install Atlas from the Microsoft Store, Microsoft knows you acquired an app, under Microsoft's own privacy policy; that is between you and Microsoft, and it tells them nothing about the contents of your filing cabinet.
11. Changes to this policy
If this policy changes we will update this page and the date at the top. Because Atlas does not phone home, we cannot notify you inside the app, so material changes will also be noted in the release notes for the version that introduces them.
