Every heat, every hammer blow, recorded in the forge light.
Anvilrity is the record-keeper that sits beside your anvil — steel grades, heat treatment schedules, hardness numbers and project history, kept straight so your blades come out the way you planned them.
Built around the bench, not a spreadsheet.
Five toolsets that follow a piece from raw bar stock to a tempered, sharpened finish.
Project Journal
Open a card per piece with steel, technique, target dimensions and deadline, then walk it through a stage checklist while logging heats, dimension changes and progress photos as you go.
Heat Treatment Records
Capture normalizing cycles, austenitizing temperature, soak time, quench medium, tempering schedule and measured hardness — each run plotted as a cooling curve against the transformation nose.
Forge Calculators
Bevel geometry, edge angle tables, forge welding windows, fuel cost, steel mass and stock removal — plus the tempering colour guide from pale straw through to grey blue.
Steel & Tool Library
A reference shelf of carbon, alloy, spring, tool and stainless grades alongside inventory for bar stock, hammers, tongs, anvils and grinders, with condition and maintenance tracking.
Blacksmith Academy
Twelve lessons across three levels — steels, heat colour, heat treatment, geometry, damascus, ornamental work and shop economics — each with a diagram, common mistakes and a five-question test.
Daily Craft Tip
A glossary of more than 280 terms, a streaked daily tip and a competency radar that shows exactly which skills still need time at the anvil.
Read the steel by its glow.
Drag the slider to move through the forging heat range and watch the billet answer the way hot steel actually does.
The classic forging heat — steel moves easily under the hammer without wasting the heat.
This is the same chart on your bench.
Inside Anvilrity this same interactive scale maps incandescent colour straight to temperature, so you can cross-check it against tempering colours, austenitizing targets and your quench window without leaving the forge.
- Live colour-to-temperature mapping for common carbon and alloy steels
- Tempering colours from pale straw to grey blue
- Forging and welding heat windows flagged as you pass through them
Made by people who've stood at the anvil too.
Know your steel. Trust your heat. Anvilrity.
Your shop records stay in your shop.
Anvilrity is built to run entirely on your own device. It does not collect, store, transmit, sell or share any personal data, project files, photographs or usage information with us or anyone else. Everything you log — project cards, heat treatment runs, calculator results, inventory and academy progress — stays local to your phone or tablet unless you choose to export or share it yourself.
Information We Collect.
We collect nothing. Anvilrity has no account system, no sign-up form and no background telemetry, so there is no personal information, project data or device identifier for us to gather in the first place.
How We Use Information.
Because no information is collected, none is used, analyzed, profiled or sold. There is no server-side processing of your steel records, heat treatment logs or academy activity.
Data Storage.
Every project card, heat treatment record, cooling curve, inventory entry and glossary bookmark is stored locally on your device. Nothing is copied to a cloud database or remote backend that we operate.
Third-Party Services.
Anvilrity does not embed third-party analytics kits, advertising networks or tracking pixels. No usage data is passed to outside services for measurement or marketing purposes.
Data Security.
Since your forging notes and hardness readings never leave your device, they are not exposed to network interception, remote breaches or server outages on our end — the app's security posture is the security posture of your own device.
Children's Privacy.
Anvilrity does not knowingly collect data from anyone, including children, because it does not collect data from anyone at all. The app is a technical reference tool and is not directed at soliciting personal information from any age group.
Your Control.
There are no accounts to manage and nothing stored remotely to delete on our end. Uninstalling the app removes its local database, including every project, heat treatment record and calculator preference, from your device.
Changes to This Policy.
If this policy is ever updated to reflect a new feature, the revised version will be published within the app with a new effective date at the top of this page.
Contact.
Questions about this policy can be sent to privacy@anvilrityapp.com and we'll get back to you promptly.
