A short note on your data.

JuniperSlate does not collect, transmit, or share any personal information.

JuniperSlate is a visual knot-tying guide: twenty knots across boating, climbing, camping, fishing and everyday cord, each drawn stage by stage. The pages that follow describe, in plain language, what the app does and does not do with the things you type into it.

I · Collection

Information we collect

None. There is no sign-up, no login and no email capture, and no identifier of any kind is generated or transmitted.

II · Storage

What lives on your device

For the app to work, the following is kept in the operating system's local storage, on your phone, and nowhere else:

Display name and avatar — the name and mark you pick on the Profile screen.
Learned knots and favourites — which knots you have marked learned or saved.
Practice log — for each finished walkthrough: the knot, date and time, session length and the confidence rating you chose (the latest 400 sessions).
Achievements — the date each milestone was first reached.
Preferences — left-handed diagrams, rope weight, strand labels, high contrast, auto-advance, step pace and reduce-motion.
First-launch flags — whether the onboarding tour is done, and the date of first launch.

None of it is uploaded. Uninstalling the app removes every byte.

III · Permissions

What the app asks for

JuniperSlate requests no runtime permissions. Its Android manifest declares none at all, not even internet access, and its iOS configuration contains no usage-description keys.

IV · Network

What goes over the wire

The app is fully offline. The whole knot library is built into the app, so there are no servers to contact, no content downloads and no remote configuration.

V · Third parties

Who else is involved

No analytics, advertising, attribution, crash-reporting or cloud services are integrated. When you tap Share on the Profile screen, the operating system's share sheet receives a short line summarising your progress, and the app you pick then applies its own privacy policy. Nothing is shared unless you tap Share and choose a destination.

VI · Children

Younger readers

JuniperSlate is suitable for all ages and collects nothing, so it holds no data that could identify a child and raises no obligations under COPPA or the GDPR provisions on children's data. Knots are used in activities with real physical risk: children should practise under adult supervision, and climbing and rescue knots should be learned from a qualified instructor.

VII · Your rights

What you can do

Everything the app records is visible inside it, on the Progress, Profile and knot-detail screens. You can change your name and preferences or un-mark a learned knot at any time, and uninstalling JuniperSlate permanently erases all of its local storage. There is no server-side copy to request deletion of.

VIII · Revisions

Changes to this policy

If anything in this policy changes, the date at the top of the page will be revised, and material changes will appear in the app's release notes.
