Back up your profile

Every session you run is stored on your computer. Not on a server. Not in a cloud. Just in your browser's local storage. If you clear your browser data, the profile goes with it.

The site has an export button. Use it.

Where the profile lives

Your sessions, achievements, lesson bests, missed words, settings -- everything -- sits in localStorage under the key tt:profiles. It is one JSON blob. The site reads and writes it; nothing else does.

This is good for privacy. It is bad for portability. If you want the same profile on your laptop and your desktop, you have to move it yourself.

Export

Open Settings → Backup. Click Export JSON. A file downloads. The filename is guerillatype-profile-<date>.json.

The file is small -- usually under 100 KB even after months of use. Save it where you save other backups. Email it to yourself. Whatever fits your habits.

Import

On another browser, or after clearing data, open Settings and click Import JSON. Select the file. The profile loads.

Importing replaces the current profile. There is no merge. If you imported once and have since done more sessions, importing the same file again will lose those new sessions. Export before importing.

What is in the file

The export is plain JSON. You can open it in any text editor. The schema is documented at the top of src/assets/js/storage.js if you are curious. The relevant fields:

• sessions -- every session, with timestamp, mode, wpm, accuracy, and the original target text.
• lifetime -- aggregate counters.
• daily, hourly -- date-keyed activity maps.
• perKey, perFinger, perCharDetail -- the data that drives the heatmap and per-character report.
• lessonResults, challengeBests -- which lessons and challenges you have cleared.
• missedWords, missedWordsPeak -- the running list of words you mistype most.
• bookProgress -- per-paragraph completion across the library.
• preferences -- your theme, font, and toggle settings.

If you ever want to delete just one part of your history, you can edit the JSON in a text editor and import it back. Most people will never need to.

How often

If you practice every day, export once a week. If you practice a few times a month, once a month. If you only have a few sessions and would not miss them, never.

The risk is not high. Most browsers do not clear local storage unless you ask them to. But people accidentally clear data, switch browsers, change machines, or run cleanup tools. The export takes ten seconds. Do it before you need it.

Why no cloud

The site has no accounts and stores nothing on its servers. This is a deliberate design choice. The trade-off is yours: you keep full control of your data, but you have to handle backups yourself.

If you want cloud-synced profiles, the site is not for you. There are paid typing tutors that offer that. This is the one that does not.
