Privacy Policy
Effective date: September 4, 2026
Standly is a digital sheet music library and viewer for Windows. This policy explains what information the app accesses, how it is used, and how it is stored. In short: Standly works on your device. Your files, your library, and your annotations never leave it. The only information the app can send is a crash report, and only if you choose to turn that on.
What the app accesses
Standly reads PDF and image files from folders that you explicitly add to your library. It builds a local catalog of file metadata (file names, paths, sizes, and content hashes) and stores your annotations (such as markings and notes) in a local database. The app accesses files only within the folders you have chosen; it does not scan or read the file system for any other purpose.
Where your data is stored
All application data, including the catalog database, settings, and diagnostic logs,
is stored locally on your device under
%LOCALAPPDATA%\Standly.
Your original music files remain in your own folders and are never modified. None
of this data is uploaded to us or to any external service.
Diagnostic logs
Standly writes diagnostic logs (errors and crash details) to
%LOCALAPPDATA%\Standly\logs.
These logs stay on your device. They are never uploaded automatically, and they
exist to help you or support troubleshoot problems. You can open the folder from
Settings → Diagnostics and delete its contents at any time.
Crash reporting (optional, off by default)
If Standly closes unexpectedly, it saves a description of the failure to your device. Nothing is sent at that point.
The next time you open Standly, it may ask whether you want to send that report. You can accept, decline, or ask not to be prompted again. You can turn crash reporting on or off at any time in Settings → Diagnostics. If you never turn it on, the app sends nothing.
If you turn it on, we receive
- The error, including its type, message, and internal stack trace
- A short trail of recent app activity leading up to the failure
- Your Windows version and processor architecture
- The version of Standly you were running
- How long the app had been open
- The list of software components loaded inside Standly at the time, which is what makes the stack trace readable
We do not receive
- Your name, email address, or account details — Standly has no accounts
- Your IP address
- Your Windows user name, which is removed from file paths before sending
- Your computer's name
- The contents of any music file, annotation, or set list
One thing to be aware of
An error message sometimes includes the name of the file being opened when the problem occurred — for example, the title of a PDF in your library. Those names are often the clue to what went wrong, so they are not removed. If a file name would itself be sensitive to you, leave crash reporting off.
Each installation is given a random identifier so that repeated reports from the same copy of Standly can be counted as one. It is not linked to your name, your email, or anything else about you, and it is not used to track you across other apps or websites.
Because that identifier is the only thing tying reports together, we have no way to match them to a person, and so cannot locate or delete an individual's past reports on request. If you have a question about a specific report, contact us and we will help where we can.
Information collected automatically by Windows
Because Standly is distributed through the Microsoft Store as a packaged app, Windows and the Store may automatically send crash and reliability reports to Microsoft. This is standard platform behavior provided by Windows, not data collected by Standly's own code. Such reports are governed by the Microsoft Privacy Statement. This happens independently of the optional crash reporting described above, and is not something Standly controls. Standly itself sends no analytics or usage data, and never transmits your files or library contents.
Your controls
You can add or remove library folders at any time from within the app. Crash reporting can be turned on or off at any time in Settings → Diagnostics, and local logs can be opened and deleted from the same place. Uninstalling Standly removes the local catalog database, settings, and logs. Your original music files are unaffected by uninstalling.
Sharing with third parties
Standly does not sell your data, and does not share it for advertising or analytics. Two parties may receive information, both described above:
- Microsoft, through the automatic Windows and Store crash and reliability reporting that applies to any Store app.
- Sentry (Functional Software, Inc.), which processes crash reports on our behalf using their United States infrastructure — and only if you have turned crash reporting on. They act as a data processor, do not use the data for their own purposes, and reports are retained for a limited period and then deleted.
Children's privacy
Standly does not knowingly collect any personal information from children.
