Qiqqa lets you sync your data between many computers by storing your data on the web. We give you a fairly hefty 200 MB of free web library space (8000 MB if you're a Premium member). But what if you need more?

No limits

We know that for serious research you probably need unlimited storage to keep all your documents. So we've programmed the Qiqqa servers to store your documents securely using Amazon's service, which can handle any amount of data you throw at it. Hooray!

What does it cost?

The numbers really are tiny: a dollar or two should easily keep your library going for a year!

How affordable are our storage prices? Some examples for you:

• To store 500MB of docs for a month, as well as upload and download 100MB will cost you $0.13 for the month.
• A library of 1Gb will cost $0.19 to upload, $0.19 for each month you leave it with us, and $0.19 each time you want to sync the ENTIRE library to a new computer.
• A bigger library with 1.5GB of docs stored for a month, and 200MB of uploads and downloads will cost you $0.36 for the month.

What about shared libraries?

Anyone that has access to a library can top it up. This will add to the library balance, which will benefit everyone that uses the library - the docs will be stored for longer, and all library users will be able to sync their data.

What happens if my library runs out of money?

• If your total free library space is above the free limit allowance, you won't be able to sync your PDFs until a library is topped up or some of the PDFs are deleted.
• If your library has been in the red for a while and you make a payment, we won't deduct the negative balance from the payment. That means you won't be penalised for reviving a dormant library down the line. We'd prefer you topped up the existing library than started a new library from scratch!
• We do reserve the right to delete your PDFs from our servers if the balance becomes negative for too long. We don't delete your PDFs immediately, so there is a chance that your docs will still be waiting for you if you top up soon enough. In this way you avoid having to pay any upload charges again.

Great. How do I get it?

Just edit your library and click the top-up link. You can pay via PayPal account or credit card. Easy!

All the pricing details

We charge a nightly storage fee based on the size of the PDFs we are storing for you. We also charge for syncing new PDF documents to your Web Library, and fetching PDF documents from your Web Library onto new computers.

These are the costs we charge, including tax:

Storage Space	$0.19 per GB for a month (billed pro-rata nightly)
Downloads	$0.19 per GB (billed at sync time)
Uploads	$0.19 per GB (billed at sync time)

Please note that we deduct the PayPal transaction cost from your payments - this is typically $0.05 + 5% of the transaction amount. PayPal also applies a 2.5% currency-conversion spread for non-USD payments. For a $1 transaction, the total fee is around $0.10 for US users, or around $0.13 for non-US users.

We reserve the right to change these charges at any time, particularly to reflect changes in the fee structure of our providers. The costs for Amazon's S3, where we store your documents, are described here.
