Privacy policy

Last updated November 15, 2026

Vacuum is an Android app for Solana Seeker, made by Dominion Nwakanma. This policy explains what the app reads, what stays on your phone, and what little leaves it. Questions go to support@usevacuum.xyz.

The short version. Your photos, videos, files, apps and contacts are looked at on your Seeker and never sent to us. To check wallets, the app asks a public Solana server about the addresses you add. If you buy Pro, our payment server keeps your wallet address and the payment so you can restore it later. With your OK in Settings, we get anonymous usage stats and crash reports so we can make Vacuum better. There are no ads, and we never use your advertising ID.

Photos and videos

With your permission, Vacuum reads the photos and videos on your phone to find similar shots, exact copies, screenshots and large videos. It compares images and detects faces on the phone, using Google ML Kit's on-device face detection and text recognition and an on-device image model. If you add a reference photo of yourself, the app keeps face measurements from it on the phone so sets with you in them can be kept. You can delete it in Settings with Forget.

Items you delete go to your gallery's trash first. Compressed videos are saved as new files in your gallery. Google ML Kit may send Google anonymous usage and performance metrics. It does not send your images.

Apps, files and contacts

With Usage access, Vacuum reads which apps are installed, their sizes and when you last used them, so it can sort them. With storage permission, it lists large files in your shared storage. With Contacts permission, it finds repeated contacts and, when you approve, links them. All of this is done on the phone and none of it is sent to us. Removing an app always goes through Android's own confirmation.

Wallets

The wallet addresses and .sol names you add are stored on your phone. To show what you can claim, the app asks a public Solana server (RPC) about those addresses. That server sees the addresses and your IP address, as it would for any wallet app. Solana data is public by nature.

Checking a wallet never needs a signature. When you claim, your own wallet app shows the transaction and you approve it there. Vacuum never sees your private key or seed phrase, and takes no fee.

Buying Pro

Pro is paid once in SKR, through your wallet app. To sell and restore it, our payment server (on Cloudflare) receives and stores:

your wallet address and a signed sign-in message proving you own it;
the order: its amount, price, payment reference and the transaction signature;
the Seeker Genesis Token IDs held by that wallet, so Pro stays with your Seeker after a reinstall.

We keep these records for as long as needed to restore your purchase, handle refunds and meet legal duties. Payments are public Solana transactions. The server gets SKR prices from CoinGecko and Jupiter, which receive no information about you.

The app does not create an account and never asks for your name or email.

Usage data and crash reports

To learn which tools people use and fix what breaks, Vacuum sends anonymous usage events and crash reports to Google Analytics for Firebase and Firebase Crashlytics. Events include things like "scan finished", "cleanup done" with rounded sizes, "wallet added" with how it was added, and paywall and purchase steps. Google receives an app instance ID, device and app details, and coarse location from your IP address. Advertising ID collection and ad personalisation are turned off.

Once a day the app also checks in with our server. It sends a random install ID made by the app, the app version, phone model, Android version, language, total and free space in whole gigabytes, whether Pro is on, how many wallets you've added and whether notifications are on. Cloudflare tells us the country. This lets us count installs and active users.

None of this includes your photos, file names, contacts, app list or wallet addresses. You can turn it all off in Settings with Share usage data.

Notifications

If you allow notifications, Vacuum notes your free space every few hours and keeps that history on your phone only, to warn you when you're running low or when a day uses far more space than usual. To say what filled the space, it looks at what was added to your gallery that day, on the phone. It also checks the wallets you've added every few days, using the same public Solana lookups described above. News messages come through Firebase Cloud Messaging, which gives your phone a push token. You can switch each kind of alert off in Settings.

Support email

If you email us, we receive your address and whatever you include, and use it only to help you. Please don't send seed phrases, private keys or private photos.

Your choices

You can turn off any permission in Android Settings and the matching feature will stop. Uninstalling the app removes everything it stored on your phone. To ask about or delete purchase records, email support@usevacuum.xyz from any address and include the purchase wallet address. Deleting a purchase record means it can no longer be restored.

Vacuum is not meant for children under 13.
