Privacy Policy
Last updated: 13 November 2026
Silo256 is an Android app made by Ashveq LLC ("we", "us"). This policy explains what the app collects, what leaves your phone, and what we never see. It matches the app's Data safety section on Google Play.
The short version
- Your files, patterns and recovery phrases never reach us. They're encrypted on your phone and stay there.
- There's no account with us, and nothing about you on our servers.
- The free version shows ads from Google AdMob, and Google collects some device data to show them. The details are below.
What the app does
Silo256 stores your photos, videos, PDFs and Word documents in encrypted vaults on your phone. You open a vault by drawing a pattern, which is stretched into a 256-bit key. We don't have that key, and there's no backdoor: if you lose both the pattern and the vault's recovery phrase, nobody can open that vault, including us.
What we never collect
- Your files. They're encrypted on your phone and only ever decrypted in memory, inside the app.
- Your patterns, recovery phrases and keys.
- The names of your files, how many vaults you have, or anything else about what's in them.
- Your contacts, your location, or anything else outside the app.
What leaves your phone
- Ads (free version). The free version shows ads from Google AdMob, never on screens that show your files. To choose and measure ads, Google collects your device's advertising ID, device information such as the model and Android version, your approximate location from your IP address, and how you interact with ads. Google uses this as described in How Google uses information from sites or apps that use its services. We don't receive any of it about you.
- Your ad choices. In the EEA and the UK, the app asks for your consent before ads are personalised, and you can change your answer at any time in the app under Settings → Privacy choices. Anywhere, you can reset or delete your advertising ID in your phone's settings.
- App settings file. The app downloads a small signed settings file from our server (hosted on Cloudflare), which switches features on or off. The request contains no personal data. Like any request over the internet, it carries your IP address; we don't use it to identify or track you.
Nothing else leaves your phone. Android's own app backup is turned off for Silo256, so Android doesn't copy your vaults to Google or to a new phone either.
Permissions
- Photos and videos: to add the photos and videos you pick to a vault. The originals stay in your gallery until you delete them.
- Camera: only for the in-app camera, when you use it. What you take goes straight into a vault, never into your gallery.
- Microphone: only to record sound with videos from the in-app camera.
- Fingerprint or face unlock: Android checks it on your phone and tells the app only whether it matched.
- Internet: for ads and the settings file described above.
Pro (coming soon)
Pro isn't available yet. When it launches, buying it will send a purchase token, an order ID and a random install ID to our server, so it can check the purchase with Google Play. Pro will also offer optional backup to your own Google Drive, encrypted on your phone with a secret that's never uploaded. We'll update this policy before Pro is available.
Keeping and deleting your data
Everything the app stores is on your phone. Deleting a vault in the app erases it, and uninstalling the app erases all your vaults and settings. We hold nothing about you, so there's nothing for us to delete.
Children
Silo256 is meant for adults. It isn't directed at children, and we don't knowingly collect personal information from anyone under 18.
Changes
If we change this policy, we'll post the new version here and update the date at the top. If a change affects what leaves your phone, the app's update notes on Google Play will say so.
