What Meridian is
Meridian is an informational tool. It performs arithmetic on figures you enter and on inflation indices published by official statistics offices, and shows you the result.
Accuracy
Inflation and exchange-rate figures come from Eurostat, the US Bureau of Labor Statistics, the UK Office for National Statistics and the European Central Bank. They are reproduced as published and may be revised by those bodies. Everything else depends on what you enter — Meridian cannot know whether the numbers you type are right, and does not verify them against any bank or broker.
The app is provided as-is, without warranty. To the extent the law allows, the developer is not liable for financial decisions taken on the basis of what it displays.
Your account
Keep your sign-in details to yourself; you are responsible for what happens under your account. You may delete it at any time — here is how. An account may be suspended if it is used to attack the service or others.
Premium
Premium is sold as an auto-renewing subscription through Google Play at €3.99 per month or €29.99 per year, after a 14-day free trial. It renews until cancelled; cancel in the Play Store at least 24 hours before the period ends. Billing, refunds and price changes are governed by Google Play's terms. Cancelling leaves the free features and all your data intact.
Acceptable use
Do not attempt to break, overload or reverse-engineer the service, access other people's data, or resell access to it.
Changes
These terms may change; material changes will be announced in the app before they take effect. Continuing to use Meridian afterwards means you accept them.
