Privacy

This notice explains what happens to your information when you use the Seisin application and this website. In short, the application stores your data on your own computer and this website does not track you. The detail below is there so that you do not have to take that on trust.

Who is responsible

Seisin is made and operated by Abdelrahman Sheibani, an individual based in Portugal, who is the data controller for the limited processing described in this notice. You can reach him at support@getseisin.com.

The Seisin application

Everything you put into the application, including applications, offers, interview notes, resumes, cover letters, contacts and settings, is stored on your own device: on Windows under AppData\Local\Seisin, on macOS under ~/Library/Application Support/Seisin, and on Linux under ~/.config/Seisin. There is no account and no sign-in. That information is never transmitted to the controller or to anyone else, and it is not processed by us in any way, because we never receive it.

The Network feature is the one place the application holds information about someone other than you: a name, role, company, and any notes you choose to add about people you have met in your job search. That information is stored on your device in exactly the same way as everything else described above, never transmitted anywhere. If you use this feature, please be thoughtful about what you record and how you use it.

Files you import are read on your own machine. That covers a CV brought in as a PDF or Word document, and a spreadsheet of past applications brought in as CSV or Excel. Nothing is uploaded in order to be read, and the analysis the application performs on a CV runs entirely on your device. The same is true in the other direction: exports, backups and calendar files are written straight to a location you choose.

An optional account with cloud synchronisation is planned for a future version. It will be optional. Using Seisin entirely locally will remain supported, nothing will be uploaded without your choosing it, and this notice will be updated before any such change takes effect.

When the application uses the internet

The application never transmits your applications, offers, interview notes, resumes or salary information, or anything else you enter. There are four occasions on which it makes a network request, and none of them carries information about you or your job search.

• Update check. On launch, and whenever you select "Check for Updates" in Settings, the application asks GitHub whether a newer version exists. On Windows and the Linux AppImage it then downloads the new version from GitHub in the background and asks you to restart to install it. It can be switched off in Settings, under "Check for Updates Automatically", in which case no request is made on startup.
• Anonymous launch count. At most once a day, the application sends a simple counter to a service we run: the version of Seisin, the operating system and the kind of installer. It contains no identifier, no account and nothing from your job search. If you answer the optional question "Where did you hear about Seisin?", that answer is sent once with it. The count is off unless you turn it on: by ticking the box on the welcome screen, or at any time in Settings, under "Share an Anonymous Launch Count", where you can also turn it off again. We store only the totals; we do not store your IP address.
• Job posting autofill. When, and only when, you paste a job advertisement URL and ask Seisin to fill in the details, it retrieves that public page in order to read the role and company from it.
• Exchange rates. When, and only when, you select "Refresh from ECB" in the Offers rate editor, it retrieves the European Central Bank's public daily reference rates.

As with any internet request, the party on the receiving end, meaning GitHub, the job advertisement's website, the European Central Bank, or Cloudflare for the launch count, will see your IP address and may process it in its own logs under its own privacy policy. We do not keep it. All four requests are avoidable: the update check can be turned off in Settings, the launch count is only sent if you turn it on, job details can be entered by hand, and exchange rates can be edited manually.

The browser extension

The optional Seisin extension for Chrome, Edge and Firefox saves a job posting from the page you are viewing into the application on your computer. To show its save button on job postings by itself, it checks each page you open for the job details the page publishes, inside your browser. That check sends nothing anywhere and keeps no record of the pages you visit. Only when you save a job does it read the posting in front of you (the role, company, location, description and similar details) and send it to the Seisin application running on the same computer, at the local address 127.0.0.1, and nowhere else. If the application is not running, a job you choose to save waits in the extension's own storage in your browser until it is. When you first install it, it opens the page getseisin.com/extension once in a new tab, an ordinary visit to this website that sends nothing about you. Apart from that it makes no requests to us or to anyone else and contains no analytics. You can hide the save button on any site from the extension itself.

To connect, the extension asks the application and you approve it in the application's own window, or you type a one-time code shown in Settings. The connection is a random key stored in the extension and, in scrambled (hashed) form, on your device. You can disconnect a browser at any time in Settings, under Browser Extension, and removing the extension deletes its key.

The application can also keep running in the background when its window is closed, and open when you sign in to your computer, so the extension can save jobs at any time. You choose this the first time you open Seisin and can change it in Settings, under Startup. Running in the background sends nothing anywhere.

This website

This website is a set of static pages. It sets no cookies, loads no third-party fonts or advertising, contains no forms, and does not track you across other sites.

To understand which pages are read and which links people arrive from, the site uses Cloudflare Web Analytics, a cookieless measurement service. A small script from Cloudflare records each page view: the page address, the referring site, and broad device, browser and country information. It does not use cookies or local storage, does not build a profile of you, and does not follow you from site to site. We only ever see the totals, never an individual visit.

The site is hosted on Cloudflare Pages. Cloudflare acts as a processor on our behalf and, in the ordinary course of serving and protecting the site, processes technical connection data including IP addresses. Cloudflare is established in the United States, so this processing may involve a transfer of personal data outside the European Economic Area, carried out under the safeguards Cloudflare provides for such transfers, including the European Commission's Standard Contractual Clauses. Cloudflare's own privacy documentation describes its retention of that data; we do not access, query or retain those logs ourselves.

What is processed, why, and for how long

Seisin holds no database of users and keeps no mailing list. The only processing carried out by us or for us is listed here, each with its purpose, its legal basis under the GDPR and how long it lasts.

• Serving this website. Technical connection data, including IP addresses, is processed by our host to deliver and protect the site. Legal basis: our legitimate interest in serving the site securely and keeping it available (Article 6(1)(f)). Retention: held only in Cloudflare's own logs, under its retention policy; we do not access, query or keep them.
• Page-view measurement. Cookieless counts of which pages are read and where visitors arrive from. Legal basis: our legitimate interest in understanding, in aggregate, how people find the site (Article 6(1)(f)). Retention: we only ever see totals; no individual visit is kept by us.
• Anonymous launch count. Totals of which versions of the application are in use, and, if you answer it, where you heard about Seisin. Legal basis: your consent (Article 6(1)(a)), given by turning the count on. You can withdraw it at any time by turning the count off in Settings, which stops any further count being sent; withdrawing does not affect counts already sent (Article 7(3)). Retention: only the totals are kept, and your IP address is not stored.
• Email you send us. Your address and message, so we can reply. Legal basis: our legitimate interest in answering the people who write to us (Article 6(1)(f)). Retention: only for as long as it takes to deal with your message.

Seisin makes no decisions about you based solely on automated processing, including profiling, within the meaning of Article 22 of the GDPR.

Service providers

These companies process data on our behalf for the activities above. Where a provider is established outside the European Economic Area, transfers are carried out under the safeguards it provides for them, including the European Commission's Standard Contractual Clauses.

• Cloudflare, Inc. (United States). Hosts this website, provides the cookieless page-view measurement, receives the anonymous launch count, and forwards email sent to our getseisin.com addresses.
• Google (Gmail). Stores the support mailbox that email sent to our getseisin.com addresses is forwarded to, and that our replies are sent from.

The other services the application contacts, GitHub for updates, the website of a job advertisement you ask it to read, and the European Central Bank for exchange rates, are not our providers: the application contacts them directly, at your request or with your setting, and each handles that request under its own privacy policy.

Your rights

Under the GDPR you have the right to access the personal data held about you (Article 15), to have it corrected (Article 16) or erased (Article 17), to restrict its processing (Article 18), to data portability (Article 20), to object to processing based on our legitimate interest (Article 21), and to withdraw consent at any time (Article 7(3)). Because the application keeps your data on your own device, and because this site only counts page views in aggregate, there is in practice almost nothing for us to act on: your data is already in your possession, and you can export, back up or delete it from within the application at any time (to remove everything at once, use Delete All Data in Settings, under Data Management, which first offers an Excel copy and a backup you can restore). You may nonetheless exercise these rights in relation to any correspondence you have sent us, or any data processed on our behalf by our providers, by writing to the address below.

You also have the right to lodge a complaint with a data protection supervisory authority (Article 77). In Portugal this is the Comissão Nacional de Proteção de Dados (CNPD). If you are in another country of the European Economic Area or in the United Kingdom, you may complain to your own national authority instead.

We do not sell personal information, and we do not share it for advertising or any other commercial purpose. We have never done so and there is no mechanism in Seisin by which we could.

Changes to this notice

If what Seisin does with data changes, this page will be updated before the change reaches you, and the date at the end of this page will be revised. Material changes, in particular the introduction of optional accounts and cloud synchronisation, will be described here in plain terms rather than absorbed quietly into the text.

Contact

For any question about this notice, or to exercise any of the rights described in it, write to support@getseisin.com. You may also open an issue on GitHub, though please use email for anything concerning your personal data.
