AromaSynergie · Terms of use

Last updated: 7 November 2026

These terms of use apply to the app AromaSynergie, published by Sensetrails Sàrl, Villars-Champvent, Switzerland (“Sensetrails”, “we”). By using the app, you agree to these terms. If you downloaded it from the App Store or Google Play, that store’s terms also apply.

What the app is

AromaSynergie helps you make essential-oil blends from the oils you own: oil sheets, goals, recipes with drops, carrier, dilution, method and precautions, substitutes for a missing oil and shopping suggestions.

Using the app

We grant you a personal, non-exclusive, non-transferable licence to use the app on devices you own or control, for your private, non-commercial use. You may not copy, modify, resell, decompile or reverse-engineer the app, or extract its oil sheets and recipes to publish them, except where the law expressly allows it.

Free version and AromaSynergie Premium

The app is free to download. The free version gives access to every oil sheet with all its safety information, My oils, the list of blends and a selection of complete recipes.

AromaSynergie Premium is an optional auto-renewing subscription that opens every recipe, replacing an oil and the shopping suggestions. It costs 1.99 € a month or 12.99 € a year; the price in your currency, including any taxes, is shown in the store before you buy. There is no free trial.

  • Payment is charged to your Apple or Google account when you confirm the purchase.
  • The subscription renews automatically at the end of each month or year, at the price then in force, unless you cancel it at least 24 hours before the end of the current period.
  • You can manage or cancel it at any time in your App Store or Google Play account settings. Cancelling stops the next renewal; you keep Premium until the end of the period already paid. Deleting the app does not cancel the subscription.
  • Purchases are processed by Apple or Google under their terms, including their refund policies. You can restore your subscription on your other devices with Restore purchases in the app.
  • If the price changes, Apple or Google will inform you beforehand, as their rules require.

Health and safety

Essential oils are powerful substances. The app provides wellness information; it is not a medical device and does not diagnose, treat, cure or prevent any disease.

  • The app does not replace the advice of a doctor, pharmacist or qualified aromatherapist. Ask one of them if you have any doubt, especially during pregnancy or breastfeeding, for a child, an elderly person, or anyone with a medical condition or on medication.
  • Never take essential oils by mouth. Keep them away from the eyes and mucous membranes, and out of the reach of children and pets.
  • Do a skin patch test before using a blend for the first time, and stop at once if irritation or any unusual reaction appears.
  • Follow the drops, dilutions and precautions shown, and the instructions on your bottles. The app’s safety rules depend on the information you give it (age, situation, health precautions): keep them accurate.
  • Quality varies from one oil to another: use pure, properly labelled essential oils from a reliable supplier.
  • In case of accidental ingestion or a serious reaction, call your local poison centre or emergency number.

Your data

Your oils, wishlist and settings stay on your device. The app has no account and no ads. The privacy policy explains how personal data is handled.

Intellectual property

The app, its oil sheets, recipes, texts, design and name are owned by Sensetrails or its licensors and are protected by intellectual property laws.

Availability and changes

We work hard to keep the app accurate and up to date, but we cannot guarantee that it will always be error-free or available without interruption. We may change, update or discontinue features at any time; the main features of Premium remain available for the period you have paid.

Limitation of liability

The app is provided “as is”. To the extent permitted by law, Sensetrails is not liable for indirect or consequential damages, or for damages resulting from the use of, or inability to use, the app or the information it contains. Nothing in these terms limits liability for intent or gross negligence, or any rights you have as a consumer under mandatory law.

Governing law

These terms are governed by Swiss law. The courts of the canton of Vaud, Switzerland, have jurisdiction, subject to any mandatory jurisdiction available to consumers in their country of residence.

Changes to these terms

If these terms change, the new version is published on this page with its date.
