TallyLab supports the following browsers:
It's possible that TallyLab works on far more than these browsers, but these are the ones we know about.
If you choose to use TallyLab solely in local mode (i.e. without remotely syncing to our server), then you have full control over your data. You can delete any of it at any time. It is fully encrypted, so if you "log out" of TallyLab, but keep your data intact, no one will be able to read it.
Your data is stored as a single encrypted chunk of data, identified only by your public encryption key. We therefore cannot identify or look at your backed up data even if we wanted to. If you wish to delete your remote backup (which, again, no one but you can decrypt), send us your public encryption key.
