01 What DiskSpace stores, and where

DiskSpace keeps one database file inside your own Windows user profile. It contains folder paths on the drives you chose to watch, their size and file count at each measurement, the names and sizes of the largest files found, free space per drive, your settings, and diagnostic logs.

All of it stays on your PC. You can delete it at any time from Settings, or by uninstalling the app.

02 What we never receive

Everything in section 1. We do not upload, sync, back up or mirror your filesystem information, and we never read the contents of your files — only how much space they take.

There is no account system and no password. If you buy by card we hold the email address from your receipt, because that is what your licence is attached to — see section 3.

03 Purchases and licensing

DiskSpace is installed through the Microsoft Store, but Premium is purchased by card through our checkout provider. We never see your card details or billing address.

Premium purchase. The checkout provider handles payment, tax and receipts. We receive the email address on the purchase, and we store it because it is what your licence is attached to. When you activate, and roughly once a day afterwards, the app contacts our licence service and sends: your licence token, a random identifier generated for that PC, the PC's name as Windows shows it, and the app version.

That exchange never carries information about your disks. No paths, no file names, no sizes — our server validates every field against a fixed list and rejects anything else outright, so this is enforced rather than promised.

You can release a PC at any time from Premium → Release this PC, and you can ask us to delete your licence record by emailing support; a refund does the same thing automatically.

04 Operational diagnostics

To keep the app reliable, DiskSpace automatically sends a small number of anonymous operational messages: one when the app is first installed, and one each time a scan finishes. Each message contains only:

• App version, e.g. 1.0.3
• Windows version band, e.g. win11-24h2 — never your exact build
• Processor type: x64, arm64 or x86
• Whether you are on Free or Premium
• For a scan: how long it took, as a range such as 15s-60s
• For a scan: how many folders were scanned, as a range such as 50k-250k
• How many drives you watch (0–32)

If the app crashes it may also send the exception type, which component failed, and a one-way fingerprint that groups identical crashes.

There is no install ID, no account, and nothing that identifies you or your PC. It can never contain file names, folder names, paths, disk sizes, or anything identifying you. Our server rejects any message that does not match this exact list, so even a modified copy of the app could not send us more. This exists purely to catch bugs and confirm the service is healthy — we do not use it to build a profile of you.

05 Diagnostics and support

Logs are written to a file on your PC and stay there. Nothing is sent automatically.

If you email support you may choose to attach a diagnostics bundle. The app shows you what it contains first, and sending is entirely your decision.

06 Security

The database and logs live inside your Windows user profile, protected by your account's permissions. If you use BitLocker or device encryption they are encrypted at rest along with the rest of the drive. Your Premium status is cached in a blob protected by the Windows Data Protection API.

The operational diagnostics in section 04 travel over HTTPS and each message is cryptographically signed. The app never requests administrator rights.

No method of storage or transmission is completely secure, but since nothing about your files ever leaves your PC, there is very little to secure in the first place.

07 This website

This site is static. It sets no cookies and embeds no third-party fonts, scripts, trackers or advertising. We do not build visitor profiles.

08 Your rights, children, and changes

Your rights. Wherever you live, you can ask us what we hold about you, or ask us to delete it — email us and we will answer. The DiskSpace data that exists about you is the file on your own PC, entirely under your control. The operational diagnostics in section 04 carry nothing that identifies you, so there is nothing tied to you to withdraw — but you're welcome to email us with questions, and you may complain to your local data-protection authority, though we would rather you emailed us first.

Children. DiskSpace is a general-purpose utility, is not directed at children, and collects no personal information from anyone.

Changes. If this policy changes materially — in particular if any data ever starts leaving your PC — we will update this page and change the date above before that version ships.
