Privacy Policy

QR Scevio is a QR code scanner that shows you what a code contains before you act on it. This policy describes what the app does with the information it handles.

Overview

QR Scevio does not collect personal data. There is no server operated by this app, no account to create, and no identifier assigned to you or your device. The developer receives nothing about your use of the app, including whether you use it at all.

The only information the app handles is the content of the QR codes you choose to scan, and it handles that content on your device.

What QR Scevio processes

• The image from your camera, while the scanner is on screen.
• An image you select from your photo library, if you use that option.
• The text decoded from a QR code, which may be a link, Wi‑Fi details, a contact card, a phone number, an email address, or plain text.
• Three on/off preferences you set in Settings.

Everything in that list is processed on the device.

Camera access

QR Scevio asks for camera permission the first time you open the scanner. iOS shows the reason the app provides: “Scan QR codes without opening them automatically.” Camera access is the only permission the app requests.

The camera is used to detect QR codes in the live preview. The app does not take photographs, does not record video, and does not keep camera frames. Only the decoded text and the position of the code within the frame leave the camera pipeline, and both stay in memory.

If you decline camera access, the rest of the app still works and you can scan codes from images in your photo library instead.

Photo library

Choosing “scan from photos” opens the standard iOS photo picker. That picker runs outside the app, which is why QR Scevio never asks for photo library permission and never has access to your library. Only the single image you pick is handed to the app.

That image is examined for QR codes using Apple’s on-device Vision framework, then discarded. It is not copied, stored or uploaded.

QR code content

When a code is decoded, QR Scevio analyses it on the device to produce the result screen. The analysis is pattern matching against rules and reference data built into the app, including a bundled public suffix list used to identify the real registered domain of a link.

QR Scevio does not open, request, resolve or follow the link during analysis. It does not perform DNS lookups, does not expand shortened links by contacting them, and does not check the link against any online reputation service. As the app states on screen, it “analyzes links on device and never follows redirects, so the final destination cannot be confirmed here.”

Scan history

If scan history is enabled — it is on by default and can be switched off in Settings — QR Scevio records scanned web links in a database inside its own private app storage. This database:

• holds only web links. Wi‑Fi credentials, contact cards, phone numbers, email addresses and plain text are never written to it;
• keeps entries for up to 30 days or 500 scans, whichever limit is reached first, after which older entries are deleted automatically;
• is protected by iOS file encryption, so it is unreadable while the device is locked;
• is excluded from device and iCloud backups;
• can be cleared entirely from Settings, or entry by entry by swiping in the history list.

Before anything is written, the link is screened. If it contains a password, an authentication token, a session key, an email address, a login or verification code, or anything that looks like a secret, the entry is refused and the app tells you the result was not stored. That screening applies to saved links too.

Saved links

Saved links are the ones you deliberately keep by tapping the bookmark. They are stored in a separate database in the app’s private storage, protected by the same iOS file encryption, and kept until you delete them — there is no automatic expiry. You can add your own name, tags and a pin to a saved link; that text is stored alongside it.

Unlike history, saved links are included in your device backup, so that your bookmarks survive restoring a new iPhone. If you back up to iCloud, your saved links are part of that backup and are covered by Apple’s handling of it. This is the only route by which anything QR Scevio stores leaves the device, and it is your backup, not a transfer to the developer or anyone else.

Settings

Three preferences are stored on the device: whether haptic feedback is on, whether tracking parameters are removed, and whether scan history is recorded. Nothing else is persisted as a setting.

Network requests

QR Scevio makes no network requests. This is not a policy commitment that could quietly change in the background — the app contains no networking code, no embedded web view and no background transfers, so there is no mechanism by which it could contact a server. The app works fully in airplane mode.

Network activity only begins after you tap to open a link, at which point iOS hands the link to another app, such as your browser. See Opening links.

Tracking parameters

By default, QR Scevio removes common tracking parameters from links before showing or opening them: any parameter beginning with utm_, plus fbclid, gclid, dclid and msclkid. The result screen lists which ones were removed, and the open button changes to “Open Sanitized Link” so it is clear what will be opened. You can turn this off in Settings, in which case the link is left exactly as scanned.

Removing these parameters reduces what the destination site learns about where you came from. It does not make you anonymous to that site.

Third-party services

There are none. QR Scevio includes no third-party libraries, frameworks or SDKs of any kind. It contains no analytics, no advertising, no attribution, no crash reporting and no telemetry. Nothing about your use of the app is measured or reported, including by the developer.

QR Scevio does not track you across other companies’ apps or websites, and does not access the advertising identifier or any other device identifier. Its App Store privacy details declare no collected data.

Opening external links

QR Scevio never opens anything by itself. A link opens only when you tap to open it, and for anything the app has flagged as questionable, only after a second confirmation. The same applies to phone numbers, email addresses and other non-web content, which are handed to the relevant app only on your confirmation. Wi‑Fi passwords stay hidden until you choose to reveal them.

Once you open a link, you leave QR Scevio. The website you visit and the app that opens it — usually your browser — then see whatever they normally would, including your IP address. QR Scevio has no visibility into or control over what happens after the handoff.

Data sharing

Nothing is shared, sold, rented or disclosed, because nothing is collected. There is no data in the developer’s possession to share, and no infrastructure that receives it.

Data retention and deletion

• History — automatically deleted after 30 days or 500 scans, and clearable at any time from Settings.
• Saved links — kept until you delete them.
• Everything — deleting QR Scevio removes its storage from the device along with it.

Children’s privacy

QR Scevio is a general-purpose utility and is not directed at children. It collects no personal information from anyone, including children, and has no account system, messaging, social features or advertising.

This website

vguliakin.dev sets no cookies, runs no analytics, loads no fonts, scripts or images from other companies, and has no forms. Nothing you do here is tracked.

The site is hosted on Railway and served through Cloudflare. Like any web host, those providers process standard request information — including your IP address, the page requested and your browser’s user agent — in order to deliver the page and protect the service. That data is handled under their own policies and is not used by the developer for analytics or profiling.

Changes to this policy

If the app’s behaviour changes, this page is updated before or alongside the release that changes it, and the date at the top of the page changes with it. Substantive changes will be described here rather than folded in silently.
