About this app

CannNotes is a private journal for medical marijuana users. It helps you consciously manage your therapy: note down sessions, track symptoms and well-being, keep track of your dosages and supplies—all stored on your phone.

šŸ”’ PRIVACY FROM THE GROUND
• The journal works locally—no account, no cloud, no login.
• Your entries never leave your phone and we have no access to them.
• Zero ads and zero trackers. Anonymous usage statistics are completely optional—you enable them yourself; they don't contain medical data or device ID.
• Optional fingerprint, Face ID, or passcode lock.

šŸ““ SESSION LOG
• Quick entry in seconds or detailed notes.
• Strain, method (herb, vaporizer, oil, capsules, etc.), quantity in grams, rating.
• Before and after mood, duration, aromas, observations, and side effects. • Photos for entries, pharmacy documents, and templates for favorite sessions.

🧩 HOME SCREEN WIDGETS
• Quick entry with one touch, without opening the app.
• Stock status and today's sessions at a glance.
• Pin a widget directly from the app.

šŸ’Š MANAGING THERAPY
• Record your dose in milligrams of THC instead of "by eye."
• A summary of your own assessments: which entries produced the best results, and which ones produced side effects.
• Schedule and track your entries regularly.
• Dose, prescription, and well-being check-in reminders.

šŸ“ˆ ANALYSES FROM YOUR DATA
• Statistics, tolerance trends, monthly summary, heatmap.
• Your duration of action — how long your sessions lasted using a given route of administration, calculated from your entries.
• Time since your last session. • PDF report for your doctor—your entire history in one document.
• Goals and challenges, including your tolerance break (T-break).

šŸ“¦ STOCK AND BUDGET
• Purchase and inventory records, and a "last-dated" forecast.
• Space for photos of your prescription, pharmacy receipt, and receipt.
• Monthly spending and budget tracking.

🌿 KNOWLEDGE BASE
• Catalog of strains available in Poland: composition, terpene profile, and sensory description.
• Database of vaporizers and educational guides.
• Catalog of cannabis clinics with a map.

šŸŒ LANGUAGES
• Polish, English, and German.

āš ļø IMPORTANT
CannNotes is an educational journal. It is not a medical device or a source of medical advice, and does not replace a consultation. The app does not estimate the concentration of a substance in the body, nor does it predict the course of action or the results of any test. In Poland, driving after consuming THC is prohibited, regardless of the concentration. Medical marijuana is available with a prescription; the treatment is determined by the treating physician. The app is intended for adults only (18+).

Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.

    Location
  • Data is encrypted in transit
  • You can request that data be deleted

What’s new

Buying the same strain in two potencies (e.g. 27% and 29%)? They are now two separate entries: picking from the catalog saves the potency in the name, each package gets its own stash and forecast, and suggestions show the other variant even when one is already in your stash. Also fixed: opening market news from the home screen (no more "Strain not found") and completed profiles of the newest strains, incl. Black Jelly 29% and Blood Orange Kush 30%. Thanks for the reports — keep them coming!
