Privacy
Subsigno runs in your browser: the signature is built on your device and copied to your clipboard from there. Four things can reach a server, each named below — the optional opt-in, the logo finder, the analytics on the production site, and the icons a signature you send may carry. Everything else stays with you.
What stays in your browser
Everything you type is kept as a draft in your browser's local storage, under a single key (subsigno.draft.v1) holding the signature details, the look you chose and which mail app you said you use. A second key (theme) remembers light or dark. Those two keys are everything this site stores in your browser; there are no cookies.
The “Clear my data” button in the Extras panel deletes both keys and resets the editor on the spot.
A team setup link travels in the part of the URL after the # symbol, which browsers never send to any server, including ours. Creating or opening one stores nothing anywhere.
What your browser requests while you edit
The preview loads the images you point it at — your photo, logo or banner — directly from wherever they are hosted, as soon as you type the address. That request goes to your host, not to us.
The logo finder, only when you use it, sends the website address you typed to our server. The server looks the name up through Cloudflare's public DNS-over-HTTPS resolver, fetches that one page, and returns the addresses of images found on it. We keep only the address you pick — never the page, never the image. Nothing about the search is stored; an abuse limit works on a salted hash of your network address, held in the server's memory for at most an hour.
Nothing else is requested: fonts, styles and scripts are served from subsigno.com, and with the opt-in box unticked the export buttons make no network request at all.
Icons in the mail you send
Social and contact-line icons are off by default. Switched on, your signature references icon images on subsigno.com, and each recipient's mail client fetches them when the message is opened. We never log, sample or analyse those requests: the automatic request logging on our infrastructure is switched off, and the routes write nothing. Cloudflare, as the host, sees the connection in passing to deliver the file — as any host would.
Leave icons off and your signature requests nothing from us, ever.
The opt-in, and what is stored then
The opt-in checkbox appears in the Share panel and again in the dialog after an export. It is one choice — ticking either box ticks both — and it is unticked by default. If you tick it, and only then, we store: your name, job title, company, email address, phone number, the language you were using, which version of this consent text you agreed to, and the date and time. Opting in gets you 10% off your first Solvetus service.
The record is stored in a Cloudflare D1 database, together with a salted one-way hash of your network address that exists only to limit automated submissions — it is pseudonymous and it is not your address. One record per email address per day; repeat submissions fold into it.
We keep the record until you withdraw your consent or until we stop contacting people altogether. If you leave the box unticked, nothing is sent and nothing is stored.
Why, and on what basis
The purpose is to contact you about IT services and practical tips, as described next to the checkbox. The legal basis is your consent, under Article 6(1)(a) of the GDPR.
Your details are never sold, rented, or shared for anyone else's marketing.
Withdrawing consent and your rights
You can withdraw your consent at any time, and you do not have to give a reason: write to info@subsigno.com and your record will be deleted.
You also have the right to ask what we hold about you, to have it corrected, to receive a copy, and to complain to your national data protection authority — in Portugal, the CNPD.
Analytics
We count visits with Matomo, run by Solvetus on its own server in France, at analytics.solvetus.com. It is cookieless, and it records page views and clicks on outgoing links. It runs only on subsigno.com — previews and test deployments stay silent — and it honours your browser's Do Not Track and Global Privacy Control settings. Network addresses are shortened before storage, raw visit data is deleted after twelve months, no profile is built, and nothing follows you to other sites.
Hosting and processors
subsigno.com runs on Cloudflare (Workers, the D1 database and its cache). Cloudflare is a US company; as the host it processes connection data — your network address and request metadata — in passing, to deliver the site and defend it against abuse. We keep no visitor logs of our own.
The other parties in the data path are Solvetus's own Matomo server (hosted at OVH in France) for the analytics above, and Cloudflare's public DNS resolver for the logo finder's lookups. There is no one else: no advertising network, no third-party scripts, no fonts or code from anyone's CDN.
Who is responsible
Subsigno is operated by Solvetus — a brand of Ruben José Dos Santos Marques, sole trader (ENI) in Portugal; the legal notice carries the full identification. Questions about this page, or about anything stored, go to info@subsigno.com.
