Privacy Policy

Last updated: 28 October 2026

Bench Mandrel is published by Coriq AB, reg. no. 556660-2560 ("we"). This policy covers the app on both iPhone and Android, and explains what it does with information.

In short

Everything you enter – projects, photos, time, stock, sales, people and their ring sizes – is stored on your device. None of it leaves the device unless you share or send it yourself.
The app has no account of its own, no advertising and no tracking, and we do not collect statistics on how you use it. (Exception on Android: the code scanner sends technical diagnostics to Google when you scan, see Camera below.)
We do not sell your data or share it with anyone for advertising.
If you choose to link the app to your account on Silversalen, you can send photos and a few words from a project to your bench there. Only what you choose is sent, and only when you tap send. See Link to Silversalen below.

Data stored on your device

Projects, time entries, photos, notes, parts, finished pieces, quotes, markets, people (names, optional contact details and ring measurements) and settings are stored locally by the app. They are included in your phone's backup (iCloud, Google or computer) according to your own settings. You can delete any item in the app, or delete everything by removing the app.

Network requests

The app connects to the internet only to:

fetch metal spot prices and exchange rates from public price services (gold-api.com and Sveriges Riksbank). These requests contain no personal information; the services receive your IP address as part of any internet request.
open links you tap, such as chain-weave guides on external websites.
link to and send to Silversalen, if you have chosen to (see below).
on Android, when you scan the link code: Google's ML Kit sends technical diagnostics to Google (see Camera).

Link to Silversalen

The link is optional and off by default. The app works fully without it.

How it is switched on: you create a one-time code on silversalen.com (Account → Linked devices), scan it with the app and approve the link on the site. The code is valid for five minutes. Without that code and your approval, nothing is linked.
What the app stores: a key that gives the app access to your Silversalen account. On iPhone it is kept in the Keychain, on this device only. On Android it is encrypted with the Android Keystore. It is not included in backups or when you move to a new phone. The app also stores your maker name and which bench project each project last sent to.
What is sent: the app's name and device type ("Bench Mandrel · iPhone" or "Bench Mandrel · Android") when you link, so you recognise it on the site – not the name you have given your phone. After that, only what you choose under To the bench: a few words and up to six photos (scaled down), to the bench project you pick or create. Location data (EXIF/GPS) is removed from the photos before they are sent. Nothing is sent automatically or in the background.
Where it goes: to your account on silversalen.com. The entries go into your bench project and show on your page when the project is public. The text is translated automatically into the site's other languages (Microsoft Azure AI Translator).
Unlinking: in the app under Settings → Silversalen → Unlink, and on the site under Account → Linked devices. The key then stops working.
Deleting: you delete entries, photos and whole bench projects on silversalen.com under Account → On the bench. Unlinking does not delete what has already been sent.
Responsibility: Silversalen Community is also run by Coriq AB, which is the data controller for what is on silversalen.com. How Silversalen handles data is described in Silversalen's privacy policy.

Camera, photos and contacts

Camera / photos – used only when you photograph your work or add photos to a project or piece, save an image you choose to share, or scan the link code (QR) from Silversalen. The photos stay on the phone and leave it only if you share them or send them to Silversalen yourself. The link code is read on the phone (on Android with Google's ML Kit, which runs on the device), and no image is saved or sent when scanning. On Android, when the scanner is used, ML Kit sends technical diagnostics to Google: device information (manufacturer, model, Android version), the app's package name and version, performance metrics, API configuration, event types and error codes, and a per-installation identifier that is not meant to identify you or the device. Google uses it for diagnostics and usage statistics for ML Kit. It is sent encrypted (HTTPS) and not passed on to others. No image and no scanned content is sent. See Google's description.
Contacts – when you choose "Add from Contacts", your phone lets you pick one contact; only that contact's name (and details you choose) is copied into the app. The app has no access to your address book otherwise.

Sharing

When you share to Instagram, e-mail or other apps, you choose what to send and where, using your phone's share menu. Location data (EXIF/GPS) is removed from shared images.

Purchases

Pro is purchased through Apple's App Store on iPhone and through Google Play on Android. We do not receive your payment details.

Crash reports

iPhone: if you have enabled Share with App Developers in iOS settings, Apple may provide us with anonymous crash and performance reports (MetricKit). They contain no personal content.
Android: reports of crashes and of the app hanging are stored only on the phone. They contain the type of error and where in the code it happened, never text you have written. They leave the phone only if you choose to share them with us.

The app contains no third-party analytics or advertising tools. The only thing that sends diagnostics to a third party is Google's ML Kit on Android, and only when you scan the link code (see Camera).

Children

The app is not directed at children under 13.

Changes

We will update this page if the app's handling of data changes.
