Almavivo: the on-device health platform<br>The on-device health platform<br>The questions your doctor doesn’t have time to ask.<br>Almavivo runs the health-planning conversation that doesn’t fit in a 10-minute appointment. It weighs the human evidence honestly, builds you a personal plan, and keeps every answer on your device. No account, no server, no profile.

Why this matters<br>Most fatigue isn’t mysterious.<br>It’s sleep, food, movement, stress, or sometimes a real deficiency. Almavivo works through them in order of likely impact, and gives you a plan instead of a guess. Every recommendation carries an evidence tier so you can see how strong the case behind it is.
Tier AStrong evidence<br>Multiple high-quality human trials and meta-analyses converge on a clear effect.<br>Creatine. Iron in deficiency. B12 in deficiency. Plant sterols.
Tier BReasonable evidence<br>Supportive human trial data with some inconsistency or narrower indications.<br>Magnesium. Omega-3 EPA/DHA. Melatonin. Riboflavin for migraine.
Tier C/DMixed, traditional, or emerging<br>Smaller trials, narrower use cases, or long traditional use without modern RCTs. We label these honestly so you can decide.<br>L-theanine. Glycine. Ashwagandha. Reishi.
Why this is different<br>Most health quizzes are funnels for your data.<br>They look like a quiz, but every answer you give is sent to a server, stored, and tied to your name. Meanwhile the trackers running on the page quietly log your visit to your Google, Meta, X, and TikTok profiles in the background. Almavivo is built so that simply can’t happen.
Most health quizzes<br>Store your intake answers from question one.<br>Build a profile attached to your name and email.<br>Run dozens of trackers, pixels, and ad-network beacons.<br>Generate recommendations on a server that sees everything you typed.<br>Sell, share, or merge your health data with other parties.
Almavivo<br>Almavivo never receives them. Every answer stays in your browser.<br>No account. No login. No profile.<br>Zero third-party scripts. Enforced by a strict browser policy.<br>The recommendation engine runs on your device. Nowhere else.<br>We have nothing to sell, because we don't have it.
The one moment data moves<br>Only if you choose to share it.<br>At the end of your plan, you can choose to print it, save it as a PDF, or send a structured summary to a health professional you select. Nothing happens automatically. Almavivo doesn’t send the email. Your own mail client does. You see exactly what is leaving, and where it’s going, before anything moves. If you don’t click send, nothing leaves your device. Ever.<br>Read how the consented share works →<br>How Almavivo works<br>Not AI. A deterministic, rules-based engine. Auditable, line by line.<br>Almavivo is a transparent set of rules, the kind a clinician or pharmacist could read, argue with, and verify, running on your device. No language model writes your plan. Nothing you type is sent to OpenAI, Anthropic, Google, or any other model. Give the same answers twice and you get the same plan twice. That’s a property of rules. It is not a property of AI.
01Deterministic<br>Same inputs produce the same outputs, every time. No randomness, no temperature, no “creative” phrasing. The engine is a pure function over your answers.
