SMS emergency alert with flash SMS right on the lock screen.
If your check-in is missed, your emergency contact sees the alert immediately on their lock screen — no app, no inbox to open. Sent from Germany via seven.io, GDPR-compliant.
Two visible channels, one clear alert
Once your check-in is missing past the defined time window, Corlo sends each of your up to five emergency contacts a flash SMS and a standard SMS in parallel — alongside the email channel. It does not matter which channel is currently open: one of the paths will reliably reach the person.
Flash SMS visible in seconds
Flash SMS appear right on the lock screen, no dismiss needed. With audio signal — even when the SMS app is closed.
Standard SMS as backup
In parallel with the flash SMS, a regular SMS lands in the inbox — so your contact can read the message again later.
Sender ID "CorloApp"
Your emergency contacts see at a glance who the message is from. Clearly identified, not an anonymous short code.
Email needs an app to be opened. Flash SMS is already there.
An email lands in the inbox and waits — possibly between newsletters and ads. A flash SMS shows up immediately on the lock screen. That is why Corlo combines both channels in the premium plan: email as a reliable primary path, SMS as an immediately visible additional path.
Up to 5 emergency contacts notified in parallel — no one is left behind if one contact is asleep or unavailable
Two SMS per contact: one flash SMS and one standard SMS — both with sender ID "CorloApp"
Monthly limit: up to 10 SMS per 30 days — enough for a full alert cycle to all 5 contacts
Email delivery runs independently — it stays active even if the SMS channel fails
SMS provider from Germany — no US cloud in the alert path.
seven.io from Kiel
Our SMS delivery runs through seven.io GmbH in Schleswig-Holstein — a genuine German provider, not an EU rebrand of a US company.
Data processing agreement under Art. 28 GDPR
We have a data processing agreement with seven.io. There is no transfer to third countries such as the US in the alert path.
Phone number used only where needed
Your emergency contact’s mobile number is used only for sending alerts, not for ads, not for profiling.
Best-effort channel, communicated honestly
SMS is a best-effort channel — we do not promise guaranteed delivery. If an SMS fails, email delivery continues independently.
Monthly limit as a fairness guardrail
Up to 10 SMS are sent per 30-day period — enough for a full alert cycle to all 5 contacts, while preventing misuse.
