Privacy policy
Who is the data controller
Make Algo SL, Tax ID (NIF) B88875018, Calle General Pardiñas, 114 — 28006 Madrid, Spain. Email: hola@make-algo.com.
There are three moments when we process your data, and they are different: when you write to us, when you subscribe and when you use echo on your Mac. They are set out separately because they have nothing in common. Apart from those is what only happens if you authorise it: the app's usage metrics.
If you write to us
What we collect. Your email address and whatever you tell us in the message. The email opens with the subject already filled in and two optional questions in the body —what you use echo for and whether you pay for Claude or ChatGPT—, but you decide what you answer and what you add. This website has no form and no database behind it: the message arrives in our mailbox and stays there.
What for. To read and answer your message, and to use what you tell us to understand how echo is used and improve it. Nothing else: no mailing list, we won't write to you afterwards, no newsletter, no advertising, no sharing your data with third parties and no automated decisions with legal effects on you.
Legal basis. Your consent (Art. 6(1)(a) GDPR), which you give by the very act of writing to us. You can withdraw it at any time by writing to hola@make-algo.com; withdrawing it does not affect the processing carried out until then.
How long we keep it. Just long enough to reply and, at most, 12 months from your last message. If you ask us to delete it sooner, we delete it.
If you subscribe to echo
What we collect. Your email address, the licence key we issue to you, an identifier of each Mac where you activate it, the activation dates and the record that you accepted the terms when purchasing. We never see or store your card details: Stripe processes the payment from start to finish.
The Mac identifier is a cryptographic digest of its internal serial number: it doesn't contain your name or say who you are, but it is tied to your licence, so we treat it as personal data and not as anonymous data.
What for. To issue your licence, so that echo can check it is still valid, to limit each key to the number of Macs you subscribed for, to help you if there is a problem, and to meet our accounting and tax obligations.
Legal basis. The performance of our contract with you (Art. 6(1)(b) GDPR). The record of your acceptance of the terms and the invoicing also rest on compliance with legal obligations (Art. 6(1)(c) GDPR).
How long we keep it. For as long as you have the subscription and, afterwards, for the periods required by tax and commercial law, which run up to six years. That is why, if you ask for erasure during that period, what we do is block your data —it is taken out of use and kept available only for the tax authorities or a court— and erase it when the period ends. This is what Article 32 of the Spanish Data Protection Act (LOPDGDD) allows.
If you only try echo and don't buy. We keep only that Mac's identifier and the date the trial started, so that the 14 days can't be restarted by reinstalling. Basis: our legitimate interest in the free trial working as advertised (Art. 6(1)(f) GDPR); the data doesn't identify you on its own and isn't used for anything else.
If you use the referral programme. When someone subscribes with your code, we store that relationship (their subscription, your key and the code) to apply their discount, credit your balance and check there is no cheating (for example, inviting yourself with another email address or the same card). Of your invitees you will only see figures: how many people have used your code and how many rewards you have earned. We will never show you their email, their name or any other data, nor show them anything of yours. If you save an invitation code during the free trial, we remember it together with your Mac's identifier so we can apply the discount if you subscribe.
When you use echo on your Mac
Your voice never leaves your computer. Speech recognition runs entirely on your Mac, offline.
If you turn on AI polishing, the transcribed text does leave, but not towards us: echo runs on your Mac the official Anthropic or OpenAI application, which sends that text with your own account, just as if you had pasted it into their chat yourself. We don't see it, receive it or store it. That transfer is governed by the privacy policy of Anthropic or OpenAI, depending on which you use. If you'd rather nothing leaves, turn polishing off: echo keeps working.
echo checks for new versions. To do so it requests, every few hours, a file hosted on this same website, which gives our hosting provider your IP address and the version you have installed. That information doesn't reach us, and you can turn off the automatic check in Settings.
Recordings stay on your Mac. echo can save the audio of your dictations so that you can compare recognition engines, but it comes turned off and, if you turn it on, those files don't leave your computer. The same goes for the activity log that echo writes in your logs folder.
App usage metrics (only if you say yes)
We ask you when you set up echo, with two buttons and nothing pre-selected. If you say no, or don't answer, no identifier is created and nothing is sent: you don't appear in any record of ours. You can change your mind at any time in Settings › Usage metrics.
What we count if you accept. Which setup steps you have completed and where you stopped, whether you reached your first dictation, and how many dictations, polishes and errors you make per day. Also the echo version, the macOS version, which recognition engine you use and which account you polish with. It is sent once at launch and once an hour, in a batch.
What we never count. What you dictate, the audio, which app you paste the text into, your window titles and your IP address. The list of what can be sent is closed both in the app and on our server, and anything not on it is discarded on arrival. The rule we follow to decide whether something can be measured is: would it allow reconstructing what someone dictated or where they pasted it? If the answer is yes, it isn't measured.
The identifier is pseudonymous, not anonymous. It's a random number created when you accept; it doesn't derive from your machine or its serial number, and it is never linked to your licence's Mac identifier or to your email. But it stays with that installation over time —it's what lets us see whether people still use echo weeks later—, so we treat it as personal data and don't sell it to you as anonymous.
Legal basis. Your consent (Art. 6(1)(a) GDPR). Withdrawing it isn't just stopping the sending: when you turn it off, echo asks our server to delete what that installation had sent, and it is deleted. What remains are counts with no identifier in them, because by then they are nobody's data.
How long we keep it. For as long as the product exists or until you withdraw consent, whichever comes first.
Who else processes your data
We work with four providers, each for one thing:
- GitHub, Inc. (United States) hosts this website and the update feed. Like any hosting, it processes the technical data of your visit —for instance, the IP address— to serve the pages and protect them.
- Google (United States) provides the email service our mailbox runs on. Your message is sent by your own email program, with your provider.
- Cloudflare, Inc. (United States) provides the licence server. The database is hosted in its European region.
- Stripe processes payments and handles your card details, which never pass through our systems.
All four are certified under the EU–US Data Privacy Framework, the European Commission's adequacy decision that covers those transfers (Art. 45 GDPR). Beyond this, we don't share your data with anyone unless legally required.
Your rights
You can ask us for access, rectification, erasure, objection, restriction of processing and portability by writing to hola@make-algo.com. We will reply within one month at most. If you are a customer, bear in mind the blocking for tax retention periods explained above. If you believe we haven't handled it properly, you can lodge a complaint with the Spanish Data Protection Agency (www.aepd.es).
Cookies
This website uses no cookies, neither its own nor third parties'. If that ever changes, we will update this policy and, where the law requires it, ask for your consent first.
How we count visits
We want to know how many people visit this website and how many download echo, so when you open a page your browser tells us which page you opened, which website you came from and from which country. With that we add one to a counter, and that's it: we don't store your IP address, which browser you use, or any identifier that distinguishes you from someone else, so we can't reconstruct your visit or recognise you if you come back. Nor do we give it to anyone: the counter is on our own server and this website loads no third-party scripts —no Google Analytics or anything like it—.
We do this on the basis of legitimate interest (Art. 6(1)(f) GDPR): knowing whether the website is any use, which is the minimum needed to improve it. As it is an aggregate count, that interest doesn't compete with any right of yours, because no data that is yours remains. The counters are kept for as long as the product exists.
The terms of service are in the terms of use and subscription.
