Sustain, focus, measure, and refine.
Arzenal brings daily rhythm, focused work, supplement context, and understandable metrics into one local-first Android companion.
A personal operating surface, not another data silo.
Arzenal starts with the details you already manage: what you take, when you intend to take it, how a routine holds up, and how a day feels. Local storage remains the source of truth, so the practical parts of the product remain available offline.
One calm place to keep a routine in view.
Inventory, recurring stacks, reminders, check-ins, and period summaries are designed as readable personal records—not as a prescription engine or a black-box health score.
Track the moments that shape a day.
Each surface reflects an implemented product workflow. They remain informational and user-directed—not clinical recommendations.
Keep the cabinet clear
Add supplements and drinks manually, from supported barcode lookups, or through an explicit label-scan flow with confirmation before anything becomes part of inventory.
Build routines you can revise
Create morning, training, evening, and night routines from scratch or templates, then log taken, skipped, and check-in context without losing the record of the plan.
Make reflection deliberate
Run local focus sessions with tasks, tags, voluntary distraction logging, and a post-session review. Arzenal does not monitor device activity or infer concentration in the background.
Keep elapsed time in context
Use an opt-in timer and personal check-ins to organize a fast. Phase language is educational estimation only—not a measurement of metabolism or a reason to change prescribed care.
Record rest without overreaching
Log sleep locally or read compatible sleep context through an optional, read-only Health Connect bridge. Manual records and imported device data remain intentionally distinct.
Ask with boundaries
Optional AI convenience is constrained to an explicit action and a compact snapshot of your own records. Deterministic safety signals and package labels remain the authority for sensitive details.
A trend should show its uncertainty.
Arzenal's Human Index is a versioned, local personal-trend calculation. It makes coverage, confidence, and missing signals visible—and can remain unavailable when the record is too thin.
Personal trend only
The Human Index is not a medical score, diagnosis, prognosis, or measure of human worth.
Local calculation
The current result is calculated from authorized and user-entered signals on the device; it is not sent to the AI layer or written to a cloud health-summary backup.
Missing is not zero
Absent data stays absent. A score is withheld rather than manufactured from a gap in coverage.
Useful context should not require indiscriminate collection.
Arzenal uses consent and scope as product constraints. The app is designed to make the limits of each data path understandable before a person opts in.
ON DEVICE
Inventory, routines, focus sessions, manual sleep, fasting records, and deterministic safety context stay local-first.
OPTIONAL HEALTH CONNECT
Android Health Connect reads are permission-gated and read-only. Arzenal does not write records back to Health Connect.
NARROW CLOUD CONSENT
Authenticated cloud backup is separate and default-off. It is limited to daily summaries; raw device samples, source details, notes, and the Human Index stay out of that backup.
Four workflows, one daily rhythm.
Move from focused work to supplement context and legible metrics without turning your personal record into a black box.
Context is not clinical care.
Arzenal offers educational organization, self-reflection, and deterministic safety context. It does not diagnose, treat, prescribe, or replace professional medical advice. Product labels, medication questions, changing symptoms, and personal health decisions belong with a qualified healthcare professional.
Fasting phases and caffeine timing are broad educational estimates, not measurements. The Human Index is a product-defined personal trend, not a medical or human-value score. These boundaries are kept visible because a confident interface should never overstate what it knows.
A clear product needs clear limits.
- What is Arzenal Human Health?
- Arzenal is a local-first Android companion for organizing supplement routines, focus sessions, fasting, sleep, and optional device-health context. Its core tracking remains usable without a cloud account.
- Is Arzenal medical advice or a diagnostic tool?
- No. Arzenal provides educational organization, reflection, and deterministic safety context. It does not diagnose, treat, prescribe, or replace a qualified healthcare professional.
- What happens to my health data?
- Core records are kept on the device. Health Connect access is optional and read-only. Any cloud backup is a separate, default-off consent for limited daily summaries; raw samples and the Human Index do not leave the device through that backup.
