Symptom Trend

Request Expert Review

Symptom Correlation Matrix

How your weekly symptoms move together — darker green means they tend to rise and fall together, darker red means one tends to rise as the other falls.

Symptom & Trigger Overlap

How often your tracked conditions show up together week to week.

Extended Symptom Trends

A wider view of your weekly trends — use "Add symptoms" to choose which ones to compare.

Encrypted Backups

Files from here (and the "Download" button on a consultation below) always end in .enc and are not ordinary ZIP files — a regular archive tool can't open them, and there's no password prompt from your OS. Decryption only happens on this page, using the "Decrypt a File" tool below.

Download an Encrypted Copy

Save an encrypted copy of your export straight to your own device — including any DNA subset you've analyzed below, if you've chosen one. Nothing is uploaded or sent anywhere; this stays entirely on your machine.

Decrypt a File

Open an .enc file you downloaded from here (or from a consultation below) using the one-time password that was shown when it was created.

DNA & Genetic Markers

Exploratory research tool — not a diagnostic or clinical genetic test. Visual Snow Syndrome has very limited dedicated genetic research. The markers checked here come from a small, conservatively-curated panel drawn mostly from migraine-with-aura and neuro-excitability literature — the closest well-studied neighbours to VSS — not a validated VSS gene panel. Rare channelopathy genes (CACNA1A, ATP1A2, SCN1A) that cause familial hemiplegic migraine aren't included as specific markers here: consumer DNA kits only genotype common population variants, not the rare mutations in those genes, so a "not found" result would be misleading. Nothing here should be used to make medical decisions — talk to a genetic counselor or clinician about anything you find meaningful.

Your raw DNA file is parsed entirely in your browser. It is never uploaded on its own — there is no separate DNA upload. The only way any of it leaves your device is bundled inside the same encrypted file you send when you submit a consultation request below.
