Why you should document your flat

Moving is stressful enough without a fight over your security deposit. Still, most tenants know the drill: on handover day the landlord wants to hold back part of the deposit because of scratches on the floor or marks on the walls. You know those defects were already there when you moved in. But without a proper handover report with photos, it's your word against theirs.

With Kaution Sichern you build your handover report straight from your phone. On move-in day you photograph every room and record existing damage to floors, walls and windows. The app logs meter readings for electricity, gas and water along with their serial numbers, documents the key handover by count and type, and lets tenant and landlord sign right on the screen. On move-out day you export a polished PDF report with every photo, timestamp and signature.

All your data stays on your device. No account, no server, no cloud. Tenancy details are sensitive, and they are nobody else's business but yours.

Three situations most renters recognise

Scratches that were already there

You move into a new flat. The floor has a few marks, you think nothing of it, you take no photos. Three years later, on your way out, the landlord points at those exact spots and demands 600 EUR to sand them down. Without photos from move-in day, it's your word against his.

Meter readings nobody verified

The handover is quick. Keys swapped, paper signed, done. Six months later the utility statement arrives: a 400 EUR bill for back-charges. The previous tenant's meter reading is written on it, but you have no way left to check whether it was ever right.

The letter after five months

You moved out ages ago and haven't heard a thing. Just before the six-month deadline runs out, a recorded letter arrives with a list of alleged damages. With no move-out report in hand, you've got nothing to push back with.

Same pattern in all three: without documentation, you lose. With photos, meter readings and signatures on move-in and move-out day, the money stays where it belongs - with you.

Frequently asked questions

Will the app help me get my security deposit back?

Timestamped photos and a handover report signed by both tenant and landlord are your strongest arguments in any deposit dispute. The more thoroughly you document the flat's condition on move-in day, the harder it gets for a landlord to withhold your deposit without cause.

What should an apartment handover report include?

A complete handover report covers: the condition of every room with photos, meter readings for electricity, gas and water, the number and type of keys handed over, any existing defects, and the signatures of tenant and landlord. Kaution Sichern walks you through each step.

Does the app work without internet?

Yes, Kaution Sichern runs 100% offline. All photos, data and signatures stay only on your device. No server, no cloud, no data sharing. You don't need an account or registration to use it.

How much does Kaution Sichern cost?

Timestamped photos, meter readings, key logs, witness entries and digital signatures are unlimited and free. No subscription.

Which languages does the app support?

Kaution Sichern is fully translated and usable in 24 languages - every official EU language. That makes it a good fit for international tenancies where tenant and landlord speak different native languages.
