Synadd, including its website and the Synadd browser extension (“the Service”) is operated by KludeOn Limited, Companies House 10413781(“The Operator”). It is our policy to respect your privacy regarding any information we may collect while operating our products and services. If you have questions about deleting or correcting your personal data, please contact us.
The Operator cares deeply about your privacy.
We follow these principles:
We don't ask you for personal information unless we need it to improve the user experience.
- We don't share your personal information with anyone except to comply with the law , protect our rights, or develop our products.
- We aim to make it as simple as possible to control what information other users and the public can see about you.
 Sadly, the applicable law in most countries doesn't respect privacy anywhere near as much as they ought to. We'll try our utmost to do the right thing, but since governments have guns, we can't make any promises.
What information we collect
Access to this information is restricted to system administrators. For support purposes, the Synadd staff has limited access to user data (email, username, active status, message sent, payment details). The Operator doesn’t share user information with advertisers, affiliates or partners nor monetise its user traffic in any way. In each case, the Operator collects such information only insofar as is necessary or appropriate to fulfill the purpose of the visitor's interaction with the Service. Users can always refuse to supply personally-identifying information, with the caveat that it may prevent them from engaging in certain Service-related activities.
We may collect device-specific information, such as your hardware model, operating system version, unique device identifiers, browser type, browser language, referral URL, or mobile network information especially via the user of third party analytics tools such as Google Analytics.
When you use the Service, our server logs may collect certain information about your activities, including details of content you viewed, the date and time of each request, and IP addresses.
In order to provide the best user experience, we collect data about your interactions with the Service, for example making a purchase of the service, looking at the different tiered options.
We may collect and store information (including personal information) locally on your device using mechanisms such as browser web storage (including HTML5) and application data caches.
Cookies are small pieces of text sent to your web browser by a website you visit. A cookie file is stored in your web browser and allows our service to recognize you. Cookies allow us to remember if you’re logged in and if you were annotating privately, in a group, or publicly.
How we use the information
We use the information we collect from our users to maintain, protect and improve our services, and to develop new ones. We use information collected from cookies and other technologies to improve your user experience and the overall quality of our services.
Handling user data
We don't save any passwords, we only save a temporary access token (OAuth Token) passed in by Google or Twitter. No Operator staff member has access to user passwords. Synadd staff has access to user emails only for support purposes.
User IP address, browser info, device info and so on will be collected by 3rd party analytics services according to their policy. This de-identified information is used for internal metrics and operational support, but we do not track your individual activity on the Synadd extension or the API. On third parties:
The Operator doesn’t share user information with advertisers, affiliates or partners nor monetize its customer traffic in any way.
Access to annotation data
There are a few ways in which a user’s annotations are available to other users:
- Information about user annotations shared in public channels like Twitter and potentially available on our feed are visible to every user of the Service
- User annotations will be directly visible when a user visits a website that another user has annotated.
The same applies to our API users: authenticated users can only retrieve annotations for which they have the right permissions. Unauthenticated users can only retrieve public annotations.
With respect to the Operator’s staff, a small number of engineering staff have database access that lets them see any annotation or profile data in your account, in order to operate the service and address problems with the system. Staff is not allowed to re-disclose private user information.
Chrome extension permissions
The Synadd extension for Chrome will ask users to grant certain permissions at the time of installation via a notification from the Chrome browser. The extension needs them in order to work with the user’s browser and the websites the user visits.
Chrome overstates what Synadd needs permission to do — we don’t use your camera, for example. We ask for these permissions because the extension needs them in order to work with your browser and the websites you visit. However, our intention is only to access the minimum permissions we need to in order to do these things on your behalf, and nothing more. We don’t monitor, track or collect any of your personal data beyond what is necessary for creating, saving and reading your annotations. Synadd does not generate revenue from advertising or from selling metrics to third parties.
The language and definition of these permissions are set by the Chrome browser, and they are meant to tell users what the kinds of data the extension will be able to access. (To read more about Chrome extensions permissions there’s a great article about it in Lifehacker, and much more technical documentation at the Chrome website).
This is how we use permissions in the Chrome extension:
- Read and change all your data on all websites you visit: we ask this so that we can inject the annotator code into the page and interact with the text on it, add and read annotations. We don’t read or modify any other data.
- Access your browsing activity: we need this to maintain the state of the Synadd extension on windows or tabs you have open. We also need this is to be able to tell you (via the extension badge) when a page you visit has been annotated. We don’t keep track of what you do in the browser.
- Communicate with cooperating websites: this permission is used to communicate with the Synadd website to know, for example, if you have the extension installed or not.
Your privacy is very important for us and we’re trying our best to ask you for as little information as we can. If you have any questions or would like some more details, please write to firstname.lastname@example.org and we’ll help you out!
Contact with users
We send account registration, activation and password reset notifications via email. We also send event notifications such as about replies to annotations via email, with the option to opt-out.
When you contact us, we may keep a record of your communication to help solve any issues you might be facing. If you send us a request (for example via a support email or via one of our feedback mechanisms), we reserve the right to publish a de-personalised, anonymised version of it in order to help us clarify or respond to your request or to help us support other users.
We may process personal information on our servers in any country in the world, and therefore cannot guarantee that your information will be processed or stored on a server located in the country where you live.
When we share the information
We do not share potentially personally-identifying or personally-identifying information with outside parties unless one of the following circumstances apply.
With your consent
We will share personal information when we have your consent to do so. This will always be done on an opt-in, rather than an opt-out, basis. In other words, we will not assume that we have your consent.
With our service providers
We disclose such information only to those of our employees, contractors, and affiliated organizations that (i) need to know that information in order to process it on our behalf or to provide services available at our websites, and (ii) that have agreed not to disclose it to others.
Some of those employees, contractors and affiliated organizations may be located outside of your home country. By using our websites, you consent to the transfer of such information to them. We will not rent or sell such information to anyone. We do not share user information with advertisers, affiliates or partners. We do not monetize our user traffic in any way.
For legal reasons
We will share personal information with outside parties outside if we:
- are required to do so by law
- believe in good faith that access, use, preservation or disclosure of the information is reasonably necessary to protect the property or rights of Synadd, third parties or the public at large
- detect, prevent, or otherwise address fraud, security or technical issues
In a depersonalised, aggregated way
We may share statistics about the behaviour of visitors to our websites. We may display this aggregated information publicly or provide it to others.
Accessing and updating your personal information
Whenever you use our services, we aim to provide you with access to your personal information. If that information is wrong, we strive to give you ways to update it quickly or to delete it — unless we have to keep that information for legitimate business or legal purposes.
Transparency and choice
People have different privacy concerns. Our goal is to be clear about what information we collect, so that you can make meaningful choices about how it is used.
We take all measures reasonably necessary to protect against the unauthorized access to, use of, alteration of, or destruction of personal information.
