How it works

Two steps to a returning client.

Create a reminder, get a QR code, clients come back on their own.

For you, the business

Fill in 3 fields → get a QR code → the client chooses themselves.

For your client

Three steps to the first reminder. No app required.

01

Client scans the QR

They land on your branded page - no app, no signup ceremony. Just your logo and your reminders.

yourco.krindo.eu
02

Chooses reminders

The client picks reminders - ticks one or more, enters email or phone, and confirms via the link in the email.

Return in 4 weeks
Yearly check-up
Seasonal promo
Confirm reminder
03

Reminders go out on schedule

At the right time - they come back. Cancellation is one click via signed link, no password ever.

For business

One QR code. Clients who return by themselves.

Stick a QR on a door, a poster, a vehicle or a receipt. Clients land on your branded page, choose what reminders to receive, and get messages when it matters - no manual chasing.

①

Your branded page

A stable URL for your company (yourco.krindo.eu). Customers see your name, not ours. Print it on anything.

[ yourco.krindo.eu - branded landing ]
②

Reminders, your rules

Define reminders - "return in 4 weeks", "yearly check-up", "filter swap" - and only show the ones that are active right now.

[ admin - reminder rules ]
③

Clients choose themselves

Clients tick the reminders they want, enter email or phone, and pick a "count from" date. Confirmed by email.

④

Manage many clients

Import your client list, manage reminders and view basic stats - all in one place.

⑤

Ships in two languages

Lithuanian and English - all out of the box. Customers see notifications in their own language.

Why it works

Better than calling and reminding yourself.

Manual follow-ups take time, get forgotten, and annoy clients. KrinDo sends reminders automatically - the client chooses when and what to hear about.

Manually
  • Calling the client
  • Spreadsheet or calendar
  • Easy to forget
With KrinDo
  • Automatic email
  • Client opts in
  • No effort from you
01

On time, without your effort

Reminders go out automatically - no calendar tracking or phone calls from you.

02

The client opts in

They scan the QR, pick reminders and leave an email - no app and no password.

03

One-click unsubscribe

Clients can cancel any time from the email - no awkward call or complicated process.

04

Fewer missed visits

The reminder arrives when it matters for them to return - not when you have time to send a message.

FAQ

Frequently asked questions

Does the client need an app?

No. They scan the QR, enter email, and get the reminder.

Do I need a password?

Not at first. Email only to save your QR.

Do you send SMS?

Email by default. SMS can be added later as an optional add-on.

How does a client unsubscribe?

Clients cancel with one click in the email - no login required.

Can I import clients?

Yes - on larger plans.

What counts as a "client" for pricing?

A contact you send at least one active reminder to. Inactive or unsubscribed contacts don't count toward your plan limit.

What happens when I hit my plan's client limit?

You'll get an email notice and can upgrade to a bigger plan at any time - existing reminders keep working without interruption.

Do you guarantee reminders reach clients?

Emails are sent through a reliable delivery infrastructure, but like any email, they can occasionally land in spam - we recommend clients check the first time.

Where is my clients' data stored?

In the European Union, GDPR-compliant. You stay in control - you can export or request deletion of your data at any time.

How do I cancel my KrinDo account?

Email us - we'll cancel it any time, with no extra fees or notice period.

Privacy policy

This Privacy Policy explains how KrinDo (the “Service”) collects and processes personal data when you use our website, admin panel, and related features. The Service is operated by Interaktyvus, MB, company code 304440352, VAT payer code LT100010635311 (“we”, “us”).

Data controller: Interaktyvus, MB, registered address Ašmenos 1-oji g. 12-54, LT-44499 Kaunas. For privacy-related requests, contact us at hello@krindo.eu or +370 618 75191.

This policy applies to business users who register an account, their staff, and end customers who choose reminders through a tenant's public page. Tenant businesses act as independent controllers for their clients' data; we process that data on their instructions as a processor where applicable.

We may process: account details (name, email); company profile and branding; client contact details and reminder preferences supplied by tenants; technical logs (IP address, browser, timestamps); communications you send us; and billing records if you purchase paid features.

We use personal data to provide and secure the Service, send transactional emails (e.g. verification and reminders), improve reliability, comply with law, and-only with consent where required-send product updates.

Under the GDPR we rely on: contract performance (providing the Service); legitimate interests (security, fraud prevention, product improvement); legal obligation; and consent where applicable (e.g. optional marketing).

We keep data only as long as needed for the purposes above, to meet legal obligations, or until you delete your account or request erasure, subject to backup and audit cycles (typically up to 90 days after deletion).

We share data with infrastructure and communications providers (hosting, email delivery such as OneSignal or SMTP, analytics if enabled) strictly to operate the Service. We do not sell personal data.

If data is processed outside the European Economic Area, we use appropriate safeguards such as Standard Contractual Clauses or providers certified under applicable frameworks.

You have the right to access, rectify, erase, restrict, object, and port your data, and to withdraw consent. You may lodge a complaint with the State Data Protection Inspectorate of Lithuania (VDAI). We will respond to requests within one month.

We apply technical and organisational measures appropriate to the risk, including encryption in transit, access controls, and regular updates. No method of transmission over the Internet is 100% secure.

We use essential cookies for sessions and security. Optional analytics cookies, if used, will be described in your browser and can be managed through your device settings.

The Service is intended for businesses and is not directed at children under 16. We do not knowingly collect children’s data.

We may update this policy. Material changes will be posted on this page with an updated effective date. Continued use after changes constitutes acceptance.

KrinDo is a software platform that lets businesses collect client email addresses via QR codes and send automated reminders. Features and limits may change; we will use reasonable efforts to notify account holders of material changes.

You must provide accurate registration information. Sign-in is via email link - no password required. You are responsible for activity under your account. We may suspend access for suspected abuse or non-payment.

If you onboard clients, you are responsible for having a lawful basis to contact them, providing required notices, and honouring unsubscribe or erasure requests for your audience. You must not upload unlawful content or spam.

You may not reverse engineer the Service, interfere with its operation, use it to distribute malware or illegal content, or exceed fair-use limits. We may remove content or accounts that violate these Terms.

Free and paid tiers may apply as published on the website. Paid plans are billed according to the pricing shown at purchase. Fees are non-refundable except where required by law.

We aim for high availability but do not guarantee uninterrupted access. Maintenance, third-party outages, or force majeure may cause downtime.

We retain all rights in the Service, software, and branding. You retain rights in your content. You grant us a licence to host and process your content solely to operate the Service.

To the maximum extent permitted by law, we are not liable for indirect or consequential damages. Our aggregate liability for any claim is limited to the fees you paid us in the twelve months before the claim, or EUR 100 if you use a free plan.

You may stop using the Service at any time. We may terminate or suspend access for breach of these Terms or non-payment, with notice where reasonable.

These Terms are governed by the laws of the Republic of Lithuania. Disputes shall be resolved in the courts of Kaunas, Lithuania, unless mandatory consumer rules provide otherwise.
