Privacy

Erlangly, the software

• Everything you put in Erlangly (people, schedules, time off, agent states) stays on the server you run it on. We never receive it, and there's no telemetry.
• The only call your Erlangly server makes to us is a daily update check: it asks get.erlangly.com for the latest version number and sends nothing about your install. Like any web request, it reveals your server's IP address. You can turn it off under Settings → System.
• Licence keys are checked on your server, offline. Each licence is activated once on its install, through an admin's browser rather than the server: the browser takes the key's id (never the key itself), a random id Erlangly made for the install, and the install's address to store.erlangly.com, and brings back the code that activates it. The store keeps them with the licence's record (below). Activated with typed codes instead, it gets no address.
• Email and your ACD's connection go only where you set them up to.
• You're responsible for the personal information you keep in Erlangly, as the organisation that collects it. We aren't your processor for it, because we never receive it. The one exception is anything you choose to send us for support (below).

This website

• Google Analytics counts visits and the pages people read, and a few things a visit leads to: the schedule template downloaded, the Erlang C calculator used, Install it free followed, an email to us, or a link to our store followed for a trial, the free plan or buying (not what happens there) (see below).
• No ads on this site. The only other thing loaded from anyone else's servers is Cloudflare Turnstile's check on the Erlang C calculator (next).
• The Erlang C calculator works out its answers on our server and keeps none of your numbers. Our web server logs each request to it with your IP address, the time and the page, and the calculator logs the IP address of anyone it bans; neither log ever has what you typed in, and like the site's other logs (below) they keep only their most recent entries. Shared links keep the numbers after a #, which browsers never send to a server. To keep it for people rather than scripts, the first answer of a visit needs Cloudflare Turnstile's check, which runs in your browser from Cloudflare's servers and sees your IP address and browser (Turnstile's privacy policy). The calculator also counts answers by IP address to limit how many each can get. It keeps those counts and any short ban in memory only, for a day at most.
• We advertise on Google Search. Analytics passes those few things to Google Ads, so we can see which of our ads lead somewhere and which aren't worth paying for. It's for that measuring only, never for showing you ads here or anywhere else. Nothing you type into the calculator or the template is sent.
• Every page you open passes through our web server and the proxy in front of it, and both keep ordinary web logs (IP address, page, browser, the page you came from, time) for security and to put problems right. They aren't kept for a set time: older lines are overwritten as new ones come in, and each log keeps only its newest 10 MB (so do the last few versions of the site and store, until newer ones replace them).

Cookies

This site sets Google Analytics' cookies, so we can see how many people visit, which pages they read and what our ads lead to:

• _ga: tells one visitor from another, without saying who you are. Kept for 2 years.
• _ga_JB76L00DL6: keeps track of your visit. Kept for 2 years.
• Only if you came from one of our Google ads, one whose name starts with _gcl: remembers that ad click, so Google Ads can count what it led to. Kept for 90 days.

Google Analytics also receives your IP address, browser and the pages you visit; Google's privacy policy covers what it and Google Ads do with them. You can turn it off: the site works the same without it, nothing is counted for our ads either, and your choice is remembered in your browser's storage, not in a cookie.

Turn off Analytics in this browser

The Erlang C calculator sets one cookie of its own, calculator_pass, once you've passed its human check, so you aren't asked again for 30 minutes. It's signed by our server, works only from the IP address that got it, is sent back only to the calculator's page, and holds nothing about you. Turning off Analytics doesn't affect it.

Our store, store.erlangly.com, sets one cookie of its own, which its forms need to work safely. It's gone when you close your browser. When you ask for the free plan or a trial from your Erlangly's activation screen, it sets a second, for 2 days: it remembers which install asked, so that opening the link in our email in the same browser activates it there. Stripe's pages, where you pay and manage your licence, set Stripe's own cookies.

Free licences, trials and purchases

When you ask for a free licence or a trial, buy a licence, or activate one at store.erlangly.com, we keep:

• Your organisation's name, the email address you gave us (and its domain) and your country.
• For a free licence: when you asked for it and confirmed your email, and when you accepted the licence agreement and which version.
• For a trial: when you asked for it and confirmed your email, when it ends, the reminders we sent, and when you accepted the licence agreement and which version.
• For a purchase: the plan, the number of agents, whether it's at the regional price, the billing country, when you paid and until when, renewals and any that failed, cancellations, refunds and their amounts, Stripe's references for them, and when you accepted the licence agreement and which version. If you start buying but don't pay, we keep what you chose and Stripe's reference for that checkout.
• For a test licence: the licence it's for, and its keys.
• For each activation: the licence it's for, the key that activated it, the install's random id and its address, when it was activated, and when and how it was moved or freed. While you're asking for the free plan or a trial from an install, we keep that install's id and address with the request until the link we email you expires.
• Whether you ticked “Send me Erlangly news” on the page the link in our email opens, and when. It starts unticked.
• Every licence key we send you, and what it says: your organisation's name, the number of agents and its dates. The key carries your organisation's name to your own server, where Settings → License shows it.

We use it to send your keys, to give each organisation one trial and one free licence (by the domain of your work email address), to keep each licence to one install and show you where it's activated, to renew, re-send or replace keys, to answer you about your licence, to check who the regional price is for, and for our accounts and taxes. We email you about your licence: the link to confirm your email, your keys, when your licence is activated on an install it wasn't on, the links you ask for to free an install or get a test licence, two reminders before a trial ends, and anything about a payment. Erlangly news, a few emails a year, only if you ticked the box for it; each has a link to stop them.

You pay on Stripe's own page, so your card never reaches us. Stripe keeps your name, billing address, any tax number you give, and your payment details, and makes your invoices and receipts. The store's log records each visit's IP address, browser, page and time, but not your name or email address, unless an email to you can't be sent. To stop repeated tries, the store also remembers the IP address that sent each of its forms, for up to two weeks.

When you ask us for help

What you send us (an email, a log, a diagnostics file, a screenshot, or an export we asked for) is used only to answer you. It's kept in our mailbox. We aim to delete files you send once your question is answered, and within 90 days, and to keep the emails themselves only as long as your free licence, trial or purchase records (below). Send only what we ask for: Erlangly's diagnostics file masks people's emails and names, and its log leaves out passwords and, since 0.8.124, the links from invitation and password emails, but can hold email addresses, so look it over first. If your organisation needs a data processing agreement for what it sends us, write to privacy@erlangly.com.

Who handles it for us

We don't sell your information or share it with anyone else, except where the law requires it. These services handle it for us:

So your information may be stored and used outside Canada, mostly in the United States, where courts and authorities may be able to ask for it under their own laws. Each handles it under its own terms of service and privacy policy.

How long we keep it

• Purchases and their keys: as long as the licence can be used, and at least six years after your last payment, as Canadian tax law requires.
• Free licences, test licences and activations: as long as the licence exists, so each organisation gets one free licence and each licence runs on one install.
• Trials that don't lead to a purchase: we keep them so each organisation gets one trial, and aim to delete them two years after the trial ends. A free licence or trial request whose email is never confirmed, and a checkout that's never paid: we aim to delete them after 30 days.
• Emails with us: we aim to keep them only as long as the free licence, trial or purchase records they belong to, or two years after we last wrote to each other.
• Files sent for support: we aim to delete them once your question is answered, and within 90 days.
• Web and store logs: overwritten as new ones come in (the newest 10 MB of each log).
• Google Analytics: the details of each visit for 2 months; after that, only totals.
• Postmark: the emails it sent for us, for 45 days.

Your rights

You can ask to see what we keep about you, to correct it, to have a copy to take elsewhere, or to have it deleted. You can also object to how we use it. Write to privacy@erlangly.com, and we'll answer within 30 days. We can't delete what the law makes us keep (purchase records for taxes), or take back a key that's already on your server.

If you're in the European Union or the United Kingdom: we use your information to give you what you asked for (a free licence, a trial, or a licence and its keys, and activating them), to keep the records the law requires, with your consent for Erlangly news if you ticked the box for it, and in our legitimate interests in giving each organisation one trial and one free licence, keeping each licence to one install, reminding you before a trial ends, and keeping our servers secure.

If you're not happy with our answer, you can complain to the Office of the Privacy Commissioner of Canada, or to the data protection authority where you live: in Quebec, the Commission d'accès à l'information; in the European Union or the United Kingdom, your country's.
