3. Our representative in the European Union

Mostly Tiny Ltd is established in the United Kingdom. We are appointing a representative in the European Union under Article 27 of the EU GDPR and will name them here. Until then, people in the EU can contact us directly at privacy@mostlytiny.io.

4. Datos personales que recopilamos

Recopilamos: información que proporcionas directamente (por ejemplo your email and optional display name (from your Mostly Tiny sign-in); your templates, uploaded images and files, and the data you send to fill them; the images and PDFs we render; pages you screenshot or check, HTML you convert; hashed API keys and usage; webhook addresses; a billing record for paid plans (cards stay with Stripe); support requests; request logs; and, with consent, how you arrived); información que se recopila automáticamente cuando utilizas mostlyrender.com, como tu dirección IP, tipo de dispositivo y navegador, páginas visitadas e identificadores de cookies; e información que recibimos de terceros cuando sea relevante.

Recopilamos datos personales en las categorías anteriores para los fines establecidos en esta política.

5. Where we get your data

Besides what you give us, we receive your sign-in identity and plan from Mostly Tiny ID, payment status from Stripe, and the content of the web pages you ask us to screenshot or check with the Open Graph checker. We have no advertising partners.

6. Cómo y por qué utilizamos tus datos

Utilizamos tus datos personales para: proporcionar, operar y mejorar mostlyrender.com y nuestros servicios; crear y gestionar tu cuenta; responder consultas y proporcionar soporte; personalizar tu experiencia; enviar mensajes de servicio y, donde está permitido, de marketing; mantener el servicio seguro y prevenir fraudes; y cumplir con nuestras obligaciones legales.

7. Lists of people you upload

With generators you can upload a list of people — for example guests' names, titles, companies, email addresses and photos — and render a card or badge for each one. You decide what the list contains and why: you are the controller of that data and we process it on your behalf, only to render your outputs, under our Data Processing Agreement.

If you turn on a Batch QR code for a generator, we send MostlyQR only the fields you choose, so each person gets their own code (and, if you choose, a profile page). When you delete a row, its details are erased from MostlyQR too, and when we delete an archived generator (30 days after you archive it) so are the rest; each code then points to your batch's archive page.

How long we keep it: an uploaded CSV or zip file until we have read it; the rows and images read from it for 30 days after upload; the details of each row until you delete that row or your account, or until we delete the generator (30 days after you archive it); and a generator's outputs, manifests and zip files for 30 days (free plan) or 90 days (paid plans).

If you are on someone else's list, contact the business or organiser that uploaded it first.

8. Screenshots of other websites

When you use the screenshot feature, our servers load the web address you give us and capture it, as a browser would. That website sees a request from our servers, not from you. We only load public web addresses, and you are responsible for having the right to capture and use the page you point us at. Our fetcher identifies itself as "MostlyRender/1.0 (+https://mostlyrender.com/bot)".

9. Free tools (Open Graph checker and HTML to image converter)

Our free tools at mostlyrender.com/tools work without an account. When you check a page with the Open Graph checker, our servers load the address you enter once, read its link-preview tags and the start of its preview image, and send the result back to you. That website sees a request from our servers, identified as "MostlyRenderOGCheck/1.0 (+https://mostlyrender.com/tools/og-image-checker)". We do not keep the address or the result.

When you use the HTML to image converter, our servers render the HTML you paste and send the image back to your browser. We do not keep your HTML or the image. Before it renders, Cloudflare Turnstile checks that the request comes from a person rather than an automated program. To do that, Cloudflare processes your IP address and technical details of your browser and connection (such as its user agent). Cloudflare acts as our processor for this check, and as an independent controller when it uses these signals to improve its bot detection, as described in its Turnstile privacy addendum (cloudflare.com/turnstile-privacy-policy).

To keep the tools free, we limit how often each one can be used. We count your requests under a keyed hash of your IP address, a scrambled form that cannot be turned back into the address without a secret key we hold, and each count is deleted automatically after its time window (one hour for the checker, one day for the converter), usually within about two days. We do this in our legitimate interest in preventing abuse of a free service.

10. How we learn where visitors come from

Fathom Analytics counts visits to mostlyrender.com without cookies and without identifying you, including which website, campaign or AI assistant referred a visit. In the UK we rely on the statistical-purposes exception in the Privacy and Electronic Communications Regulations. You can object at any time by switching off "Analytics" in Cookie settings, which turns Fathom off for your browser.

We also keep our own anonymous daily totals of visitors who arrive from an advert: how many land, open our editor, sign up and buy, by ad platform and landing page. The ad platform and page name travel in the web address of our own pages; nothing is stored on or read from your device, no cookie is used, and the totals are never linked to you or your account. Because no storage on your device is involved, this counting continues whatever you choose in Cookie settings.

If you accept Analytics or Marketing cookies, our site also remembers in your browser how you first and most recently arrived (campaign tags, the referring site and the page you landed on) and attaches it to your account when you sign up, so we can see which channels bring us customers. If you do not accept, we keep none of this. The one exception is a referral code, if you followed a friend's referral link: we keep it only to credit that referral.

When you sign up, subscribe or cancel, our servers record that event against your account in PostHog (EU), to measure how our business is doing. We rely on our legitimate interests for this; you can object by emailing privacy@mostlytiny.io.

11. Emails we send you

We email you what you need to use MostlyRender: sign-in links, receipts, billing and security notices, and messages about your account. These are part of the service, so you cannot turn them off while your account is open.

We may also send you tips and offers about MostlyRender. The sign-up form has a box for these, ticked by default: untick it and we never send them. In the UK this is the "soft opt-in" in regulation 22 of the Privacy and Electronic Communications Regulations; our lawful basis under the UK GDPR is our legitimate interest in telling customers about the product they signed up for, and you can object at any time.

We email you about other Mostly Tiny products (MostlyQR, MostlyPDF, MostlySign, MostlyPrivacy and Vekta) only if you asked us to, by ticking a box that is never ticked for you, either when you sign up or later in a product. Our lawful basis is your consent. We send at most one such email a month across all of them.

Every marketing email says why you are getting it, has an unsubscribe link, and supports your email app's one-click unsubscribe button. One click stops that kind of email; the linked preferences page lets you choose exactly what you get, or stop all marketing email from every Mostly Tiny product at once. You can also change this in your Mostly Tiny account at id.mostlytiny.io/settings. Withdrawing is as easy as agreeing, and never affects service email.

To show we had your agreement, we record each choice: which box, the exact wording you saw, when, and a keyed one-way hash of your IP address. We store your choices against a one-way hash of your email address. If an address bounces permanently or a message is reported as spam, we stop all marketing email to it. Our do-not-email list keeps only that hash, never your address, so it continues to protect you after you close your account.

12. Nuestras bases legales para el procesamiento

Si se aplica el GDPR de la UE o del Reino Unido, procesamos tus datos personales conforme a una o más bases legales bajo el Artículo 6: tu consentimiento, la ejecución de un contrato contigo, el cumplimiento de una obligación legal, la protección de intereses vitales, la ejecución de una tarea de interés público, o nuestros intereses legítimos (o los de un tercero), excepto cuando tus intereses o derechos prevalezcan.

Cuando nos basamos en intereses legítimos, estos incluyen operar y asegurar nuestros servicios, entender cómo se utilizan, y marketing limitado — puedes objetar en cualquier momento. Cuando procesamos categorías especiales de datos personales bajo el Artículo 9 (por ejemplo, datos de salud o biométricos), lo hacemos solo con tu consentimiento explícito u otra condición permitida por la ley.

13. Con quién compartimos tus datos

Compartimos datos personales con: proveedores de servicios y procesadores que operan mostlyrender.com en nuestro nombre (por ejemplo Google Cloud and Firebase: hosting, sign-in, database, file storage and rendering (where, see "Where your data is stored"); Stripe: payments; Resend: email; Fathom Analytics: cookie-free statistics; PostHog (EU): product analytics in the app; Cloudflare: Turnstile, the bot check on the free HTML to image converter; MostlyID: sign-in and the shared billing record; MostlyQR: tracked short links for dynamic QR codes you add to a template, and a personal code for each row when a generator creates a Batch QR; and MostlyPrivacy: this cookie banner and these documents), quienes solo pueden usarlo según nuestras instrucciones; asesores profesionales, proveedores de pago, y agencias de aplicación de la ley o reguladores cuando sea necesario; y partes en una transacción corporativa como una fusión o adquisición. No vendemos tus datos personales por dinero.

14. Transferencias internacionales de datos

Algunos de nuestros proveedores de servicios se encuentran fuera de tu país, incluso fuera del EEE, el Reino Unido o Australia. Cuando transferimos datos personales internacionalmente, confiamos en un mecanismo de transferencia legal — como una decisión de adecuación, las Cláusulas Contractuales Estándar de la UE (con la Adenda de Transferencia de Datos Internacionales del Reino Unido donde corresponda), u otra salvaguarda permitida por la ley — y tomamos medidas para mantener tus datos protegidos. Los detalles están disponibles bajo solicitud en privacy@mostlytiny.io.

15. Where your data is stored

MostlyRender runs on Google Cloud and Firebase: database in the United States (nam5 multi-region); rendering, uploads and rendered outputs in the UK (europe-west2, London).

Sign-in uses Firebase Authentication, which Google runs only in the United States, and a Mostly Tiny account you sign in with is held by Mostly Tiny ID, whose database is in the United States. Our website is served from Google's global network (Firebase Hosting).

Transfers to Google LLC in the United States rely on the UK Extension to the EU-US Data Privacy Framework (and, for data under the EU GDPR, on the EU-US Data Privacy Framework), to both of which Google LLC is certified. If you are in the EU, your personal data reaches our servers in the UK under the European Commission's adequacy decision for the UK (Implementing Decision (EU) 2021/1772, as amended by Implementing Decision (EU) 2025/2574).

16. Cuánto tiempo conservamos sus datos

Conservamos datos personales solo el tiempo necesario para los fines descritos en esta política; después los eliminamos o anonimizamos. Los criterios que utilizamos para establecer períodos de retención incluyen la naturaleza y sensibilidad de los datos, el propósito del tratamiento, y nuestras obligaciones legales, contables y de reporte (templates and uploads until you delete them or your account; rendered outputs for 30 days (free plan) or 90 days (paid plans), at unguessable public web addresses you can embed and share; lists of people: see "Lists of people you upload"; usage for the current and previous billing periods; billing records as tax law requires; request logs briefly for security; free-tool counters up to two days).

17. Cómo protegemos sus datos

Utilizamos medidas técnicas y organizativas apropiadas —incluida la encriptación en tránsito, controles de acceso y revisión periódica— para proteger datos personales contra pérdida, mal uso y acceso no autorizado. Ningún método de transmisión o almacenamiento es completamente seguro, por lo que no podemos garantizar seguridad absoluta.

18. Cookies y tecnologías similares

Utilizamos cookies y tecnologías similares en mostlyrender.com. Para obtener información sobre las cookies que utilizamos, su propósito y duración, y cómo controlarlas, consulte nuestra Política de Cookies.

19. Toma de decisiones automatizada

No tomamos decisiones que produzcan efectos legales o igualmente significativos sobre usted basadas únicamente en el tratamiento automatizado, incluida la elaboración de perfiles, a menos que lo permita la ley. Si alguna vez lo hacemos, le informaremos, explicaremos la lógica involucrada y le ofreceremos el derecho a obtener revisión humana.

20. Privacidad de los menores

mostlyrender.com no está dirigido a menores. No recopilamos conscientemente datos personales de menores por debajo de la edad de consentimiento digital que les aplica (16 conforme al GDPR, sujeto a edades nacionales inferiores hasta 13), y no vendemos ni compartimos conscientemente la información personal de consumidores que sabemos son menores de 16. Si crees que un menor nos ha proporcionado datos, contacta con nosotros en privacy@mostlytiny.io y los eliminaremos.

21. Tus derechos conforme al GDPR

Si el GDPR de la UE o el UK GDPR te aplican, tienes derecho a: ser informado; acceder a tus datos personales; rectificar datos inexactos; suprimir tus datos; limitar el tratamiento; la portabilidad de tus datos; y oponerte al tratamiento, incluido el marketing directo. Cuando el tratamiento se basa en el consentimiento, puedes retirarlo en cualquier momento sin afectar al tratamiento realizado con anterioridad.

Para ejercer cualquiera de estos derechos, contacta con nosotros en privacy@mostlytiny.io. Responderemos en el plazo de un mes, que podemos prorrogar hasta dos meses más para solicitudes complejas o numerosas, informándote en el primer mes. También tienes derecho a presentar una reclamación ante tu autoridad supervisora de protección de datos.

22. Autoridad supervisora del Reino Unido

Si estás en el Reino Unido, te aplican el UK GDPR y la Data Protection Act 2018, y puedes presentar una reclamación ante la Information Commissioner's Office (ICO) en ico.org.uk.

23. How to complain to us

If you are unhappy with how we have handled your personal data, email privacy@mostlytiny.io with "Complaint" in the subject. We will acknowledge your complaint within 30 days, look into it, and tell you the outcome without undue delay. You can also complain to the Information Commissioner's Office at any time.

24. If you are in the United States

We do not sell or share personal information for advertising, and we treat a Global Privacy Control signal from your browser as a refusal of any non-essential cookies. To ask what we hold about you, or to have it corrected or deleted, email privacy@mostlytiny.io.

25. Cambios a esta política

Podemos actualizar esta Política de Privacidad de vez en cuando. Publicaremos la versión actualizada aquí con una nueva fecha de vigencia y, donde los cambios sean significativos, tomaremos pasos razonables para notificarte.
