This acknowledgement accompanies the JotaTron application download. It does not replace any licence or third-party notices supplied with the release.
Download registration
To request the application or sample database, you must provide a full name and email address. The private download register also records the requesting IP address, selected file and server-generated UTC time. Read the download privacy information before continuing.
Back up your data
You are responsible for maintaining appropriate backup copies of your notebooks and checking that they can be restored. Computer faults, storage failure, accidental deletion, corruption or software interruption can result in data loss. Autosave and a backup are different things, and a backup can only contain information saved by the time it was made.
Keep at least one suitable copy separate from the computer holding the working notebook. Before deleting or replacing an original, open a restored copy under a new filename and check its notes and images.
Encrypted database passwords
JotaTron does not provide password recovery for encrypted notebooks. You are responsible for remembering and safeguarding the encryption password. Losing it means the encrypted database cannot be opened, and ordinary encrypted backups of that database still require the password that applied when they were made.
JotaTron can deliberately create an unencrypted backup after showing a warning. Such a copy preserves only the data it contains and is readable without database encryption, so it must be stored and shared carefully.
Appropriate use and care
Review exported Markdown, clipboard content and unencrypted copies before moving or sharing sensitive material because those outputs may sit outside notebook encryption. Use the maintenance and deletion controls carefully; actions identified as immediate or irreversible should be preceded by an appropriate backup.
Software availability
JotaTron is provided for use on supported Windows systems. Software and computer environments can contain faults or incompatibilities. To the extent permitted by applicable law, you accept responsibility for deciding whether JotaTron is suitable for your needs and for protecting your files, passwords and backups. C. Spencer does not accept responsibility for data loss caused by the absence of usable backups or loss of an encrypted-database password.
Nothing in this acknowledgement excludes or limits rights or liabilities that cannot legally be excluded or limited.
