REVOT, K.K. ("we") operates no server that collects your personal data through Bulwark.
Safari content blocking and the Safari Web Extension "Bulwark — Page Adjustments" work differently. The four content blockers (Ads, Trackers, Annoyances & Social, Japan & Custom) work through declarative rules: the app never learns which pages you visit, and cannot see your browsing history, URLs, or page content. The Page Adjustments extension is different — to hide elements with a tap, fix a page, or run a check, it reads page content on sites you've allowed, entirely on your device. What it reads is never sent to us or anyone else. All that's stored is the last time it ran, the rule version, and whether it's permitted; a site's name is kept only for sites where you've hidden something, fixed something, or paused protection yourself, and only on your device.
Your block log and statistics are calculated and stored only on your device. Your settings, allowlist and custom rules stay on your device, and are also stored in your own iCloud if you turn on iCloud sync — only the allowlist and custom rules sync; your block log and statistics never do. Public filter lists (EasyList family, Japanese Filters) are fetched from each publisher. Our own Japan-specific list ships bundled with the app and is not fetched from anywhere. The data the Page Adjustments extension uses (cosmetic hiding and repair rule sets) and the data the Check feature uses (the official-domain ledger and fake-message patterns) are fetched from our server (filters.bulwark.revot.jp) after checking its signature; no device-identifying information is attached to these requests.
Text, links and screenshots you check with "Check a link or message" are compared, entirely on your device, against a signed, bundled ledger of official company domains and known fake-message wording. Links are never opened, and nothing you check is sent to our servers. The Junk SMS filter examines only SMS/MMS from senders not already in your contacts, judges them entirely on your device (iPhone only), and never transmits the message text anywhere.
The one exception to all of this is an error report you choose to send from the Check screen's result: it shows you the full text before sending, then hands it to your own Mail app addressed to contact@revot.jp. It contains the domain names of the links you checked, the result codes Bulwark produced, the version of the data it used, your app and iOS version, and an optional comment you type yourself. Nothing is sent automatically, and nothing is sent without you tapping "Send."
There are no third-party analytics or advertising SDKs, and we send no promotional notifications. Purchases are processed by Apple; we never see your payment details, and purchase status is verified on-device via StoreKit. You can delete all app data by deleting the app or from in-app Settings, and manage iCloud data from iOS Settings › Apple ID › iCloud; we keep no copy on our servers. The app is not directed at children under 13 and we do not knowingly collect personal information from them. If this policy changes, we will post the new version here with an updated date.
