Your documents

The editor is a program that your browser downloads and runs. When you open a PDF, your browser reads it from your disk; when you save, your browser writes it back. No part of a document, its text, its pictures, a password or a signature is sent over the network.

Reading scanned pages and checking the layout of a page are done by helpers that are downloaded to your browser when you first ask for them. They run on your device as well.

What is kept on your device

So that nothing is lost when a window closes, a document with changes you have not saved is kept in your browser’s private storage for this site: a copy of the file, your changes, and the permission to save back into the file you opened. It is offered again when you come back. Saving or discarding it removes it; otherwise it is removed after 30 days, the next time you open the site. At most eight documents are kept this way.

Your choices are remembered in the same place: the language, light or dark, your answer about cookies, how files are saved, the colors of the mark-up tools, how you last numbered pages, and which hints you have already seen. A signature is kept only if you tick "Keep it on this device".

The editor itself is kept there too, so that it opens without a connection: the program, the fonts it has used and the extras you asked for. While a document of 64 MB or more is open, a working copy of it lies in the same storage; it is removed when you close the document, or at the latest the next time the site is opened.

A password you set for a file is kept nowhere. Clearing this site’s data in your browser’s settings removes everything listed here.

No account; cookies only if you agree

There is nothing to sign up for, so we have no name or e-mail address of yours unless you write to us. The pages set cookies for one purpose only, to count visits and see how OasisPDF is used so that we can improve it, and only if you agree. None of them are for advertising.

The site is served by Cloudflare. Like every website, the server that delivers these pages sees the internet address and browser type of whoever asks for them, and which files were asked for: a page, a font, the reader for scanned pages when you first use it. It never receives a document or anything in it.

The first time you open a page, we ask. If you decline, or do not answer, nothing is loaded from Google, no cookie is set and nothing described in the next two paragraphs happens; the site works just the same.

If you accept, the page loads Google Analytics, a service of Google. It sets two cookies: _ga holds a random number that tells a browser that comes back from a new one, and the one whose name begins with _ga_ holds the number and the start of your current visit; they are kept for up to two years after your last visit. It reports which pages of this site you open, the page that linked to them if your browser passes that on, how long you stay and how far down a page you scroll, which links to other sites you follow, that you began to fill in or sent a form, such as the contact form (never what you write in it), and the type of your browser, operating system and device, the size of your screen and the language your browser is set to. Google works out roughly where you are, down to the city, from your internet address, which Google Analytics does not keep.

We look at totals and trends, not at single visitors, and use them only to learn which parts of OasisPDF are used and what to improve. They are not used for advertising: Google’s advertising features are switched off. Google Analytics never receives a document, its name or anything in it: it is given the address and the title of the page as they were when the page opened, never the name of a file you open. Google keeps these details for at most 14 months after your last visit (the totals made from them, such as the number of visits in a month, stay in our reports), and may handle them in other countries, including the United States, under its own data protection terms.

We do this on the basis of your consent. You can change your answer at any time with "Cookie settings" at the foot of every page: declining removes the cookies, and nothing more is sent.

When you write to us

If you send a message with the form on the contact page, what you type into it (your name if you give it, your e-mail address, the topic and the message) and the language of the page are sent to us as an e-mail. The form is handled by Cloudflare, and the e-mail is delivered to a mailbox we keep with Google. E-mail you send to one of our addresses reaches the same mailbox, passed on by Cloudflare. Your internet address and your browser are not put into the e-mail.

To stop the form from being misused, Cloudflare counts the messages that come from one internet address within a minute. We do not keep that address, and nothing of what you write is counted (if you accepted cookies, Google Analytics learns only that the form was started or sent).

We use your message only to read it and answer you, and we do not pass it on to anyone else. We delete it within 12 months of our last exchange, unless we need it longer to deal with a legal claim. We handle it on the basis of our legitimate interest in answering the messages we are sent, and of your request.

Cloudflare and Google may handle this information in other countries, including the United States, under their own data protection terms.

Fonts

When a document needs a font it does not carry, the editor fetches an open font from this site. Fonts installed on your computer are looked at only if you choose "Look in my installed fonts" and allow it in the browser’s prompt. Once you have allowed it, the editor looks there again whenever a document names a font, until you take the permission back in the browser’s site settings. The list stays on your device.

Your rights

You can ask us what information we hold about you, and ask us to correct it, delete it or stop using it. We hold nothing about you unless you wrote to us, so this concerns your messages; what Google Analytics counted if you accepted cookies is held under a random number that we cannot link to you, and "Cookie settings" stops it at any time. Write to privacy@oasispdf.com, and we will answer within a month, or sooner where a law that applies to you requires it.

If you live in the European Union, the United Kingdom or another country with a data protection law, you can also complain to the authority that oversees that law where you live.

Who is responsible

OasisPDF decides how the information described here is handled: it is the "controller", in the words of data protection law. Questions about privacy: privacy@oasispdf.com.

If this policy changes, the date at the top changes with it. A change that affects how your information is used is explained here before it takes effect.
