Why you should document your rental
Moving is stressful enough – fighting over your security deposit shouldn't be part of it. But many tenants know the drill: the landlord wants to keep part of the deposit for scratches on the floor or marks on the wall. You're sure the damage was already there when you moved in. But without a proper apartment condition report with photos, it's your word against theirs.
Kaution Sichern turns your phone into a complete move-in inspection app – totally free. Walk through each room, photograph existing damage to floors, walls and windows. The app records meter readings for electricity, gas and water with serial numbers, logs the key handover by type and count, and lets both tenant and landlord sign directly on the screen. At move-out, generate a professional PDF report – with all photos, timestamps and signatures.
All your data stays on your device. No account, no server, no cloud. Rental data is sensitive – and nobody's business but yours.
Frequently asked questions
Can this app help me get my security deposit back?
Timestamped photos and a signed inspection report are the strongest evidence in a deposit dispute. The more thoroughly you document the apartment's condition at move-in, the harder it is for the landlord to withhold your deposit unfairly.
What should a move-in inspection report include?
A thorough inspection report includes: the condition of every room with photos, meter readings for electricity, gas and water, the number and type of keys handed over, existing defects, and signatures from both tenant and landlord. Kaution Sichern walks you through every point.
Does the app work without internet?
Yes, Kaution Sichern works 100% offline. All photos, data and signatures stay exclusively on your device. No server, no cloud, no data sharing. No account or registration needed.
How much does the app cost?
All core features are completely free with no limits: photos with timestamps, meter readings, key handover log, witness documentation and digital signatures. The premium upgrade for PDF export is a one-time purchase – no subscription. Buy once, use for every move.
What languages does the app support?
Kaution Sichern is fully translated and usable in 24 languages – all official EU languages. Ideal for international rental agreements where tenant and landlord speak different languages.
