Free and Pro
Exactly what a membership adds, what the apps require, and what happens when you are offline.
What is in each
Free, in a browser, with no card:
- Open every supported format — HP Tuners .hpl, Holley .dl, MoTeC .ld, SCT, Haltech, FuelTech, MegaSquirt and CSV — up to 15 MB a log.
- Graphs with zoom, pan, a shared cursor and per-channel axis ranges.
- The full channel list with live values, search and filters.
- The built-in gauge clusters, and re-mapping any gauge to another channel.

- Saving layouts and dashboards on the device you are using.
- Browsing the shared library.
Pro adds:
- Histogram tuning tables, math channels, and gauges behind a table.
- Custom gauge dashboards you build and keep.
- Comparing two logs on the same axes.
- Race zero, time slips, lap times and Dragy data.
- Using and sharing library items.
- Layouts, dashboards and tables synced to every device you sign in to.
- History of every log you open, saved to your account (1 GB).
- Logs up to 250 MB.

Pro-locked controls stay visible rather than hidden, so you can see what a membership adds before paying for one. Saving a layout is free; syncing it to your other devices is the Pro part.
Signing in and staying signed in
Sign in once with your alldatalogs.com email and password. The app needs the internet that first time to activate on this PC; after that it holds a signed statement of your membership and re-checks in the background, when you come back from sleep, and when Windows says the network is back.
Working offline is fine for 30 days at a stretch. The banner tells you when it is counting down: “Offline. Pro stays active for N more days without a connection.” Reconnect and it renews silently. Past 30 days without a check, Pro features lock until you reconnect; nothing is deleted.
A membership that is past due keeps working for a week rather than stopping dead, and one you cancel runs to the end of the period you paid for.
What the banners mean
| Offline, N days left | Normal. It is counting down the 30 days and will reset on the next check. |
| Could not verify, N days left | It reached the server but could not confirm. Get online properly, or check the membership on the website. |
| You were signed out on this PC | Sign in again. |
| This PC's clock moved backwards | Fix the date and time, then reconnect. Moving a clock back is how an offline licence would be cheated, so it is treated carefully. |
| This version is too old to verify | Update the app. |
