How licensing works
A Core purchase includes 12 months of optional feature updates from purchase (new features and improvements). Every InkSpine release has a licence date: the day the feature release it belongs to was published. A fix release has the licence date of the release it fixes. A fix release corrects problems in an earlier version and adds no new features. Any other release is a feature release. Your Core licence covers every version whose licence date is on or before the last day of your update period, which Preferences → Account shows. Apart from the confirmations described below, those versions keep working exactly as before, with Core, for as long as you like, on your registered devices, with no further payment.
A version with a later licence date is a different release and is not part of your licence. It opens on the Free tier: it still opens, edits and saves every project, and nothing you wrote is deleted or changed. Your licence is not affected by any of this.
After the first year, more updates cost half the Core price at the time, and you keep everything either way. A renewal costs no more than half the regular price of a new Core licence on the day you buy it, before any discount, in the currency of your checkout and rounded down to a whole unit of that currency; the exact amount, including any tax, is shown at checkout before you pay.
During the first 150 days after you buy Core, InkSpine confirms your licence with our server twice: once between day 17 and day 30, and once between day 121 and day 150. InkSpine does this by itself whenever it is online, and it works offline in between. If a confirmation has not been made by its date, InkSpine opens on the Free tier until it next reaches our server; nothing you wrote is deleted or changed, and your licence is not affected. After the second confirmation InkSpine does not need to connect again. If a confirmation shows that your purchase was refunded or reversed, Core stops on that device.
