Last updated: July 2026 · Covers SystemZen for macOS, Windows, iPhone, iPad, and Android

Ask us anything: [email protected] — or use the contact form.
We answer within one business day (Mon–Fri, U.S. Pacific Time).

What to include

None of this is required, but it usually saves a round trip:

Your platform and OS version — macOS, Windows, iPhone/iPad, or Android
The app version, from Settings → About
Whether you signed in with Google or with an email address and password
What you did, what you expected, and what happened instead

Please don't send us a file you were trying to clean. SystemZen works on your device and we never receive your files — we'd rather keep it that way. A screenshot with sensitive parts covered is usually enough.

A scan says I have less to clean than I expected

That is usually correct, and it is deliberate. SystemZen only reports space it can actually reclaim in places you have granted it access to. It will never inflate a number to make a cleanup look more impressive — if a competing app claims many times more, it is generally counting things it cannot safely delete. Granting access to more folders will legitimately raise the figure.

The app is asking for Usage Access or folder access

Per-app data and battery totals need Usage Access on Android to be real measurements rather than estimates, and cleaning a folder needs access to that folder. SystemZen only ever sees what you grant, and declining leaves the rest of the app working.

Why am I seeing ads?

The free tier of the iPhone, iPad, and Android apps is ad-supported; SystemZen Pro is ad-free. The Mac and Windows apps never show ads. On iPhone and iPad you can decline tracking when asked and still use the app — you will simply see non-personalized ads. What the ads collect is set out in the Privacy Policy.

I paid, but the app still shows the free tier

Open the paywall and choose Restore Purchases, making sure you are signed in to the same Apple Account, Google account, or Microsoft account you bought with. If it still does not unlock, email us the store receipt and we will sort it out.

How do I cancel my subscription?

Cancelling is handled by whoever took the payment:

Mac, iPhone, iPad: System Settings / Settings → Apple Account → Subscriptions.
Android: Play Store → Subscriptions.
Windows: Microsoft Store → Library → Subscriptions.

You keep paid features until the end of the period you already paid for. Refunds are issued by the store that processed the payment, under its own policy.

My history is not showing on my other device

History syncs per account, so sign in with the same account on both devices. Runs completed while signed out are recorded on that device only and are not backfilled after you sign in.

Delete my account and data

See Delete Your Account & Data for the in-app steps, the email fallback, and exactly what is deleted versus retained.

Reporting a bug

Tell us the steps that trigger it, what you expected, and what happened — plus the platform and app version. If a cleanup behaved unexpectedly, the section you were in and the figure it showed you help far more than the files themselves, which we don't want.
