Open Access Helper for Safari (App), Open Access Helper for iOS and https://www.oahelper.org/ are a free service, available to you at no charge.
I do my very best to limit the amount of data collected, to the absolute bare minimum and will outline what, how and when I do something below. I have compiled this information myself, I am not a lawyer, so if you have questions, let's talk about them.
The iOS version keeps a count of OA Searches, OA Found, core.ac.uk PDFs, the current number of Bookmarks (etc). If you select to share with me (this is the default), the app will communicate these values once a month to me. You will be able to see the data and the date these values were shared within the settings app. The purpose for these values is to help me understand where to invest development time, they do not contain Personally Identificable Information. The macOS App does not share information with me at this time.
If you enable the CORE Recommender feature, the app will request recommendations via this server. The data submitted will be the title of the paper, the abstract, the URL and DOI. There is no unique device id or anything that could identify you personally. My server will obtain the recommendation from core.ac.uk and then respond to you. In case we have requested recommendations for this document (based on DOI) within the last seven (7) days, we will serve the recommendation from cache.
In macOS you will see a count of Open Access articles found through the app extension. This data is collected and stored locally and never communicated outside the app.
For the purpose of this website, I do NOT set cookies, but I collect normal server logs (Apache). In these logs your IP Address has been treated, so that the last octet is removed (e.g. 10.11.12.13 will turn to 10.11.12.0). Furthermore Apache Server logs contain information submitted by your browser, such as Operating System, Browser & Version, language preferences, date and time...
otzberg.net is hosted on a virtual private server at Linode, LLC.
For the app to function I might call the following APIs
Additionally the macOS app will follow every link returned by these APIs to determine, whether you might already be at the final hosting location. This happens within the extension (app) itself. However each node in the redirect, will see your IP Address. This is not done on iOS.
If you send me an E-Mail it will be forwarded to GMAIL and is kept and stored there.
Please see information about Information Collection and use above. A sample log entry looks like this. Kindly remember that the last 0 in the IP is the anonymized IP mentioned further above:
22.214.171.124 - - [04/Nov/2018:13:34:36 +0100] "GET /oahelper HTTP/1.1" 301 553 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Safari/605.1.15"
For iOS users, who elected to share usage data with me, once a month data that is similar to this will be submitted
You will find that the above includes a UID, this uuid is a privacy conscious unique device id, issued by iOS upon developer request. Imagine two apps on your iOS device, both requesting a uuid, they would be given different uuids. The purpose of this value is to potentially see how these numbers increase over time - however at this time, this is not done.
You will notice that they are pure numbers, they don't give any indication as to who you are, what you searched for or viewed. They simply provide a crude meassure of usage and might help future feature development.
While other parts of www.otzberg.net will set and read cookies, this is not the case for www.oahelper.org
