Keep identifying details
separate from clinical notes

omdex works on a simple principle: client names and contact details should be stored separately from session notes and clinical information. Each client is identified by a code — so your scheduling and notes stay clean and anonymised, while contact details live in their own dedicated space.

SCHEDULE
Sessions, fees, payment status and CORE-10 outcomes — all referenced by client code, keeping clinical data clean and anonymised.
RECORD
Contact details, GP information, referral notes and correspondence — stored separately from session data, offline and encrypted.
TRACK
Track business income and expenses against HMRC SA103 categories, monitor your tax liability, and export a ready-to-use summary.
PROCESS
Your private reflections and process notes, kept entirely separate from your clinical records. Personal, encrypted, and always offline.

🪪
Client codes, not names Session data is tied to client codes rather than names. Contact details are stored separately in omdex-records, keeping clinical and identifying information apart.

Portable backups Export a single encrypted .json file. Restore on any device with your passcode.

Simple as it should be

Step 01 Get your licence

Purchase on Gumroad and receive instant access. No download needed — the apps live at omdex.app. Start with the free journal if you want to try first.

Step 02 Add your first client

Create a client code — initials plus a number works well (e.g. JD01). Codes keep your records anonymous to anyone who finds the file, while staying easy for you to recognise.

💡 Tip: be consistent from the start
Step 03 Set a passcode & back up

Create a passcode on first use — this encrypts all your data. Then use Save .JSON regularly to export an encrypted backup. Browser storage is not permanent; your .json is your safety net.
