Privacy Policy
Effective November 15, 2026Nix is a call and text blocking app for iPhone. It is published by DEDUSHKA DEVELOPMENT - FZCO ("we", "us"). This policy covers the Nix app and the website nixblocker.app.
What we collect
Nothing that identifies you. Nix has no accounts and never asks for your name, email address or phone number. It does not request access to your contacts, does not track you and contains no advertising or analytics software.
Calls
Nix gives iOS a list of numbers to block or label. iOS does the blocking itself and does not tell Nix who called you or which calls were blocked. Nix never sees your call history.
Text messages
When text filtering is on, iOS passes texts from unknown senders to the Nix filter on your iPhone. The filter checks them on the device and has no network access. Message text, attachments and sender details never leave your phone and are not stored by Nix.
Your lists
Numbers, number ranges and words you add in the app are stored only on your iPhone. They are not sent to us.
Spam list updates
The app downloads the spam list from data.nixblocker.app. Like any download, this request reaches our server from your IP address. The request contains no identifier of you or your device, and we do not keep logs of these requests. Our hosting and network providers may process connection data as needed to deliver the file.
Purchases
Subscriptions are bought through Apple's App Store. Apple handles payment; we do not receive your payment details or your Apple Account information.
When you contact us
If you email support, we receive your email address and whatever you choose to send, including the optional diagnostics report (app and iOS versions, dates, statuses and counts — no phone numbers, words or message text). We use it only to answer you.
Where the spam list comes from
The list is computed from public complaint data published by the U.S. Federal Trade Commission and the Federal Communications Commission. Source: United States Federal Trade Commission, www.ftc.gov. The complaints are not verified by those agencies, and neither agency endorses Nix. If your number is listed by mistake, email support@nixblocker.app and we will review it.
Children
Nix is not directed to children under 13 and does not knowingly collect information from them.
Changes
If this policy changes, the new version will be posted on this page with a new effective date.
