Spinsafe - Der Outdoor-Tresor

Spinsafe protects your valuables safely from occasional theft at the lake, the open-air swimming pool, while surfing or at the festival campsite.

This summer you finally have #oneworryless

We're working to make sure you won't have to worry about getting your valuables stolen at leisure activities out on the lawn. Whether at the swimming lake, in the park or at the festival: our outdoor vault reliably protects your mobile phone, money and keys from occasional theft. The protection is rounded off by our alarm protection app supplied. If the smartphone is in the safe, the app registers when someone tampers with it using the accelerometer. If there is an attempt to steal, the smartphone warns you and other people around with a shrill alarm.

More about the safe

That's how it's done



A special seal protects the contents of your Spinsafe from rain and splash water.

Light and portable

With a weight of 500g, the Spinsafe can easily be stored in any backpack.

Reliable protection against occasional thieves

The bottom screw creates a firm connection to the sunbathing lawn. Missing levers and the free-rotating upper shell make it even harder for occasional thieves to reach your valuables.

Protection when camping at festivals

With the Spinsafe you no longer have to leave your valuables unprotected in the tent. Just mount the Spinsafe in the awning and your valuables are safe.

Even safer with our app

Use your smartphone as an alarm system. Get our Spinafe Alarm app for iOS and Android!

Attachment of other objects

Secure further objects with a steel cable lock. For example your bicycle, backpack or dog leash.

Leaves no trace

After unscrewing, the hole caused by the Spinsafe can be closed again with two gentle foot steps.

Quality Made in Germany

All parts of the Spinsafe as well as its packaging are manufactured and assembled in Germany.


The Spinsafe itself and its packaging consist to a large extent of recycled material.

Frequently asked questions

Does the Spinsafe do harm to the lawn?

Spinsafe leaves only a small hole, which can be closed by a few footsteps. The lawn does not suffer any damage.

Where can I buy the Spinsafe?

You can buy the Spinsafe in our Online-Shop.

Can't the Spinsafe be loosened by shaking so it can be pulled out of the ground?

A conventional meadow is so firmly grown together and compacted that it provides the Spinsafe an extremely good hold. We have already been able to confirm this through tests on the series product.

Is Spinsafe also suitable for sandy beaches?

The current screw is not designed for sandy beaches. With market acceptance, however, we would like to develop an appropriately designed solution for this application.

Is Spinsafe really waterproof?

The Spinsafe is splashwater proof and keeps your mobile phone and valuables dry even in the rain.

How does the app work?

You can start the app by placing your mobile phone in the Spinsafe. This uses sensor data from the mobile phone to detect violent force against the Spinsafe. When it is registered, and thus when a potential theft attempt is detected, a shrill alarm is triggered via the smartphone's speakers. Depending on the settings of the app, the vibration alarm can also be triggered to make carrying the safe even more conspicuous.

I'm using a theft-proof bag

Theft-proof backpacks are great, but have a disadvantage on the sunbathing lawn: You always need a firmly mounted bar or similar, where you can attach the bag. This limits your choice of place very much and is also not given at every sunbathing lawn. Our advice: Simply use your Spinsafe to attach your bag 😉

I prefer to use a waterproof bag for my valuables

Waterproof shoulder bags for strapping are a good way to protect your valuables. However, you seldom get much into them. Most of the time it is only enough for some cash and the car key. And let's be honest: It's not really chic and pleasant to always go swimming with a bag strapped on

I've got a great hideout for my valuables. A thief never finds that

There are great solutions for hiding valuables. Be it in the typical hidden products like empty shampoo bottles or a cola can. Unfortunately, these are nothing more than hiding places. If someone watches you hide your belongings there, they know. Of course, thieves know exactly where to look. If you really want to be on the safe side, the Spinsafe with its triple protection is the best option.

What are our next steps?

Thanks to your help, we were able to carry out a successful crowdfunding campaign on the Indiegogo platform. The money collected helped us enormously to make the Spinsafe a reality.

In April, our supporters received their ordered Spinsafes on time. Our online shop is now open as well. There you can secure your own Spinsafe. Finally the uncertain feeling whether your valuables in the tent or in the shoe are really safe has come to an end.

I am Gero Kraus, 26 years old and I come from the beautiful Bavaria. In 2017 I completed my master's degree in computer science in Leipzig. I recently moved to Brunswick to work full-time with Dennis on the Spinsafe. In my spare time I play basketball, ride my mountain bike and also like to surf. The latter, by the way, I won't be doing without our Spinsafe again in the future. Dennis and I are giving everything, so you can do the same too soon. We met in 2011 in the Yukon (Canada) as work colleagues and have been best buddys since then. Now I am happy - as a fresh digital native - to be able to help him to market the idea of the Spinsafe online.
