myCrescent-Sickle Cell Tracker

myCrescent — The Sickle Cell Health Companion

Living with sickle cell disease means tracking more than most people can imagine — test results, pain crises, medications, appointments, triggers, and the small daily changes that matter. myCrescent is the health companion built specifically for people with SCD and those who care for them.

Everything in one place. Nothing lost between appointments.

YOUR FULL HEALTH STORY, ORGANISED

Log blood results, pain episodes, medications, hospitalisations, vaccinations, and daily check-ins — then see the patterns your care team needs to see. myCrescent turns scattered notes, photos, and memory into a clear picture of your health over time.

PRIVATE BY DESIGN

Your health data belongs to you. myCrescent encrypts your data in transit (TLS 1.2+) and at rest (AES-256) on secure UK/EU infrastructure, with an additional AES-256-GCM layer protecting sensitive fields. For maximum privacy, set an optional on-device passphrase (PBKDF2, 600,000 iterations) so only you can unlock your data.

We never sell your data. We never share it with advertisers. We never use your health information for marketing. You can export or delete everything at any time.

Rayscent Ltd is ICO-registered (ZC117860) and treats your health data as special category data under UK GDPR.

BUILT WITH THE SCD COMMUNITY

myCrescent is made by people who understand sickle cell — not a generic health tracker with a label slapped on. Every feature exists because someone with SCD, or someone caring for them, needed it.

IMPORTANT

myCrescent is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your haematologist or healthcare provider for clinical decisions.
