These terms apply to the sensea membership. They are provided by sensea GmbH, Birkenstraße 109, 40233 Düsseldorf, Germany, hello@sensea.ai (registered at the Local Court of Düsseldorf, HRB 112752, VAT ID DE461918485), "we" or "us". The purchase of sensea devices is covered by our terms of service.
1. What the membership is
The membership is what makes sensea work. It covers:
- alerts and notes to the people in your circle,
- the sensea app for your circle,
- remote verification with short heat clips,
- software updates for your devices, including security updates,
- the cloud service behind it.
You need one membership per home, however many sensea devices you use there. Everyone in the circle of a home with an active membership can use the app. Without an active membership, sensea does not send alerts.
sensea helps families notice when something at home is different. It is not a medical device and does not replace care, supervision or an emergency call system. We cannot promise that sensea notices every situation, and alerts depend on power, Wi-Fi, the mobile network and the phones of your circle.
2. How you take out the membership
You take out the membership in the sensea app, usually when you set up your first device. You buy it as a subscription through the Apple App Store or Google Play, with the account you use there. You can choose:
- Monthly: €39 / $49 a month,
- Yearly: €399 / $499 a year.
The price shown in the app before you confirm the purchase applies, including any taxes.
Founding member price. If your sensea comes from an order on sensea.ai that got the launch price (the first 300 devices, see section 1 of our terms of service), you get the membership at half the regular price: €19 / $24 a month or €199 / $249 a year, one membership per order. The app offers it when you set up your first device. The founding member price applies for as long as that membership runs without interruption, through every renewal, and you can switch between monthly and yearly without losing it. It is always half the regular price of the plan. If the membership ends, because you cancel it or it is not renewed, the founding member price ends too; a new membership then costs the regular price.
3. Payment, renewal and cancellation
Apple or Google charge you, renew the subscription at the end of each month or year, and handle payment problems, under the terms of the App Store or Google Play.
You can cancel at any time in the subscription settings of your Apple or Google account. The membership then ends at the end of the month or year you have already paid for, and sensea keeps working until then. There is no minimum term.
Refunds for the membership are made by Apple or Google under their terms. If you return all devices of a home within the 30-day return period of our terms of service, please cancel the membership as well; we confirm to Apple or Google that the devices came back.
4. Price changes
If we change the price of the membership, Apple or Google tell you before it applies to you, and where the law or their rules require it, ask for your consent. You can cancel before the new price applies.
5. Changes to the service
We keep developing sensea and may change features, as long as the membership keeps its main purpose and the change is reasonable for you. We tell you about changes that matter to you in good time.
6. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and where we have given a guarantee. For slight negligence, we are only liable if we breach an obligation that is essential for the contract and on which you may regularly rely, and then only for the typical, foreseeable damage. Otherwise our liability for slight negligence is excluded. These limits also apply to our employees and agents.
7. Your data
How we handle personal data in the app and on the device is explained in our app privacy policy. Apple and Google process your payment data under their own privacy policies.
8. Consumer dispute resolution
We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board.
9. Applicable law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not take away the protection of mandatory provisions of the law of the country where you live.
