Terms of sale
What a purchase from Corollaria gives you, and when it can be undone. Corollaria is an imprint of Tensional Labs.
What you acquire
A volume in one edition (one language), to read in Corollaria's reading room, for good, with every revision of that edition.
You read signed in as yourself; there is no file to download, and an account is for one reader.
Philosophia (Metaphysica, Ontologia and Epistemologia) is one acquisition, in one edition; a volume of it you have already paid for counts toward it.
Price and payment
Prices are set in US dollars and may be shown and charged in your currency. Any tax is shown at checkout, before you pay.
Your purchase is sold through Link, Stripe's checkout, as the merchant of record: Link takes the payment, settles any tax, sends the receipt, and its own terms apply to the payment. Corollaria never sees your card. Asked through Link's support, Link may also return a payment itself, at its discretion, within sixty days of it: what it returns in full leaves your library, and a return of part of a payment is settled by Corollaria.
Pre-orders
A volume not yet open may be pre-ordered. It is charged at once and opens to you at the moment its page names. Until then you may withdraw it in full, from your library or by writing to Corollaria; a set is withdrawn whole, while none of its volumes is open.
An edition still in preparation opens at the volume's moment, or when it is published, if later. Before the moment it is withdrawn as any pre-order; after it, on its own until it is published, in full or, from a set, at its share of the set's price. If it is not published within three months of the moment, Corollaria refunds it by itself, in full or at that share, to the card that paid, a gift included.
Refunds
Once a volume is open to you, the sale is final. A volume that counted toward Philosophia is refunded only with Philosophia. A charge made in error is put right: write to Corollaria.
Gifts
A gift becomes its recipient's when they sign in with the address it was sent to; if they already own it, it is returned to you automatically. Once received, it is theirs and is not refunded.
In the European Union and the United Kingdom
You may withdraw from a purchase of digital content within fourteen days. Acquiring a volume already open, you ask for it at once and acknowledge that your right to withdraw then ends. A pre-order keeps that right until it opens to you; withdraw from your library, or by writing to Corollaria.
Codes
A code from Corollaria opens a volume or a set to read for a time. It is reading, not ownership; it is not sold, and not refunded.

These terms may change; a purchase stays under the terms of its day. Nothing in them limits a right the law gives you, including remedies for a volume that is faulty or not as described.
