📊 CaVeSal® Prenatal Calculator
Buy your key on Gumroad, choosing the "Calculadora" version.
Within minutes you will receive an email with your access key (format XXXX-XXXX-XXXX-XXXX).
Open cavesal.app/full/ on the device where you will use it, paste your key when prompted and tap "Activar" (Activate).
Done — it is permanently unlocked on that device, with all future updates included.
📋 CaVeSal® Clinical Record
Buy your key on Gumroad, choosing the "Historia Clínica" version.
Within minutes you will receive an email with 2 keys: one for the PC/office and one for your phone. Both devices sync through Google Drive.
Open historia.cavesal.app on each device (one key per device), tap any padlock 🔒, paste your key and tap "Activar" (Activate).
Done — the 17 clinical guides, plotted curves, export and direct sending to the Calculator are unlocked.
⭐ Calculator + Clinical Record Combo
Buy the "Combo" on Gumroad — it is the best-priced option if you want both apps.
You will receive a single email with 3 keys: 1 for the Calculator and 2 for the Clinical Record (PC/office + phone).
Activate each key in its corresponding app, following the same steps above.
🚨 CaVeSal® Obstetric Emergencies
Buy your key on Gumroad, choosing the "Emergencias" version, or without a card by bank transfer.
Within minutes you will receive an email with 1 access key.
Open cavesal.app/cavesal-emergencias/full/ on the device where you will use it and install it first (Add to Home Screen).
Open it from the installed icon, paste your key and tap "Activar" (Activate). It stays enabled permanently, offline too.
⭐ Combos with Emergencies and Super Combo
Choose your combo on Gumroad or by bank transfer. You will receive a single email with all the keys:
- Emergencies + Calculator: 2 keys (1 Emergencies + 1 Calculator)
- Emergencies + Clinical Record: 3 keys (1 Emergencies + 2 Clinical Record)
- Super Combo: 4 keys (1 Calculator + 2 Clinical Record + 1 Emergencies)
Activate each key in its app, following the steps in each section above.
🤖 CaVeSal® IA
Unlike the professional apps, CaVeSal® IA is not activated with a padlock inside the app — it is a personal account (email + PIN) that you then use from any device.
Buy your plan on Gumroad, choosing "Pro", "Premium" or "Premium Plus" depending on the number of queries you need.
Within minutes you will receive an email with your activation code.
Open ia.cavesal.app, enter the code and your email, and choose the PIN you will use from then on (any PIN you like, to identify yourself). You also choose the response language (Spanish, English or Portuguese) — it is saved with your account.
Done — from then on you sign in with your email and PIN from any device (no need to enter the code again), and the "Analizar con CaVeSal® IA" (Analyze with CaVeSal® IA) button becomes available in both the Calculator and the Clinical Record.
