Our Data Processing Addendum forms part of these Terms and applies where One System Software LLC processes personal data on your behalf as a customer, within the scope described in the DPA. Our processing of personal data as controller is described in our Privacy Policy.
These Terms govern your use of Remind1. Please read them before creating an account or using the service.
One System Software LLC (“Remind1”, “the Company”, “we”, “us” and “our”) operates the Remind1 service. “You”, “your” and “Client” mean the individual or organization that holds a Remind1 account. “Party” means either you or One System Software LLC; “Parties” means both.
Eligibility and Account Authority
You must be at least 18 years old, or the age of legal majority where you live if higher, and legally capable of entering into a binding agreement to create or use a Remind1 account.
If you create or use an account on behalf of an organisation, that organisation is the Client under these Terms, and you confirm that you have authority to bind it to these Terms.
You must provide accurate account information, keep your login credentials secure, and promptly notify us if you become aware of unauthorised access to or use of your account.
We are committed to protecting your privacy and the privacy of your clients.
We process your clients’ contact details, calendar data and reminder content to provide the appointment reminder service, including reminder history and related support. We do not use this identifiable client data for our own marketing or analytics.
We use your account information to operate, support and secure your account, analyse account usage to improve the service and, where permitted by applicable law, inform you about our own similar or complementary products and services, as described in our Privacy Policy. We obtain consent where required and provide a free unsubscribe option in every marketing email.
You are responsible for establishing and documenting a valid legal basis for processing your clients’ personal data and sending appointment reminders through Remind1, providing required privacy notices, and obtaining consent where required by applicable law. Remind1 does not require consent where another valid legal basis applies. You must comply with the data protection and privacy laws applicable to your use of the service.
To provide reminders, we need information about your appointments and their participants. When you connect an online calendar, we use calendar integration authentication data to access relevant events. The calendar information we extract or use consists of client names or mobile numbers, appointment titles, dates, times, addresses and video conference links. We use this information to provide the appointment reminder service, including reminder history and related support.
If you enable calendar status updates, we also add reminder status to the relevant event in your connected calendar.
Sent-reminder history is deleted from active systems 12 months after sending. Following account termination, remaining personal data is deleted from active systems within 30 days, unless retention is required by law. Account termination does not extend an existing retention period. Cancelling a paid subscription does not terminate or delete your account; existing retention periods continue to apply.
When you disconnect a calendar, Remind1 stops using its access and refresh tokens to access that calendar. The tokens remain stored until your Remind1 account is deleted, at which point they are deleted from active systems.
We take measures to protect personal information, but transmission over the internet cannot be guaranteed to be fully secure.
Further details about our processing, sharing and protection of personal information are provided in our Privacy Policy and, where we process personal data on your behalf, our Data Processing Addendum.
We treat account records and personal data as confidential. We disclose personal data only as described in our Privacy Policy and, where applicable, our Data Processing Addendum, and we do not sell or rent it. We handle requests concerning personal data for which we are the controller in accordance with applicable data protection law. If you are the controller of appointment participants’ data, you are responsible for responding to their data-protection requests; we will assist you as described in our Data Processing Addendum. Service emails and any permitted marketing emails are described in our Privacy Policy.
Exclusions and Limitations:
Remind1 may experience interruptions or errors, including those caused by third-party calendar and messaging services. We do not guarantee uninterrupted or error-free operation.
Nothing in these Terms limits our liability for intentional or grossly negligent conduct, or for injury to life, body or health caused by negligence. For ordinary negligence, we are liable for a breach of an essential contractual obligation only up to the foreseeable loss typical for this service. Other liability for ordinary negligence is excluded to the extent permitted by law. Mandatory consumer rights and any liability that cannot lawfully be limited remain unaffected.
The exclusions and limitations in these Terms do not override our responsibility for subprocessors’ data protection obligations under Article 28(4) GDPR or exclude or restrict liability contrary to the Standard Contractual Clauses incorporated into our Data Processing Addendum. In the event of a conflict, those mandatory requirements and the Standard Contractual Clauses prevail.
The free trial is available once per user and does not require payment details. It includes 10 appointment reminders to test Remind1. When you have used all 10 reminders, the free trial ends. You may then stop using the service or subscribe to a paid plan. You cannot obtain another free trial.
Remind1 offers monthly and yearly subscription plans. The price and reminder allowance for each plan are shown before purchase and depend on your account’s country and chosen plan. Paid subscriptions are sold through Paddle, which acts as the merchant of record and authorised reseller. You purchase the subscription from Paddle, while Remind1 makes the service available under these Terms. Your purchase is also subject to Paddle’s Buyer Terms and Refund Policy. Subscription payments are taken in advance and renew at the selected monthly or yearly interval unless you cancel.
Monthly plans provide a reminder allowance for each paid month; yearly plans provide an allowance for each paid year. Unused reminders expire at the end of the applicable paid billing period and do not carry over.
If a subscription payment fails, we will retry it up to two additional times. After three failed attempts in total, your subscription will be cancelled. Your Remind1 account will remain intact, and your reminder history will remain available subject to the applicable retention periods.
You may request a full refund of your first subscription payment within 30 days after that payment. The guarantee applies to the first payment for either a monthly or yearly plan, but not to renewal payments. Any other refund rights under applicable law or Paddle’s Refund Policy remain unaffected.
You can cancel your monthly or yearly subscription at any time within your Remind1 account. Cancellation stops future renewal payments. Any unused reminders from your current plan remain available until the end of its paid billing period, when they expire. Cancelling a subscription does not delete or terminate your Remind1 account. Your account and reminder history remain available subject to the applicable retention periods. You must separately request or initiate account deletion to delete your account.
We may suspend access to all or part of Remind1, cancel a subscription, or terminate an account if:
Where reasonably possible, we will notify you of the reason and provide an opportunity to remedy the issue before suspending or terminating your access. We may act immediately without prior notice where reasonably necessary to address an urgent security risk, prevent harm, comply with law, or stop unlawful use.
Non-payment may result in suspension of paid features and cancellation of the subscription, but does not by itself delete the account. If the reason for a suspension is resolved, we may restore access within a reasonable time. Following account termination, personal data is handled according to our Privacy Policy and, where applicable, our Data Processing Addendum. Refunds are governed by the section below and applicable law.
You may cancel your subscription as described above. If you request a refund from Remind1 within 30 days after your first subscription payment, we will arrange a full refund through Paddle, even if you have begun using the service. This guarantee does not apply to renewal payments. If Remind1 ends a paid subscription before the end of its paid billing period for a reason unrelated to your breach, we will arrange with Paddle to refund the unused portion. Your other refund and statutory withdrawal rights under applicable law or Paddle’s Refund Policy remain unaffected.
Links on this website may lead to third-party sites that Remind1 does not operate or control. A link does not mean we endorse that site. Please review its content and privacy notice before sharing personal information with it. Our liability concerning links is governed by the Disclaimer above and applicable law.
Copyright and other intellectual-property rights in this website’s content belong to One System Software LLC or the relevant rights holders. You may not copy, redistribute or republish that content without permission, except where applicable law permits it.
You may reach us by messaging [email protected].
A failure by either party to enforce a provision of these Terms does not, by itself, waive the right to enforce it later. Any waiver must be clear and applies only to the specific matter waived.
These Terms and Conditions are governed by the laws of Germany. To the extent permitted by applicable law, the courts of Germany shall have exclusive jurisdiction over disputes arising out of or in connection with these Terms. If you are a consumer, this choice does not deprive you of mandatory protections under the law of your habitual residence or restrict any mandatory rights concerning jurisdiction. Rights and jurisdiction provisions under the Standard Contractual Clauses incorporated into our Data Processing Addendum remain unaffected. If any of these terms are deemed invalid or unenforceable for any reason (including, but not limited to the exclusions and limitations set out above), then the invalid or unenforceable provision will be severed from these terms and the remaining terms will continue to apply.
We may update these Terms to reflect changes to the service, law or security. We will post the revised Terms with their effective date. For a material change affecting existing users, we will give at least 30 days’ notice by email, unless a legal or security reason requires an earlier change; in that case, we will notify you as soon as reasonably possible. If you do not agree, you may cancel your subscription and stop using Remind1 before the change takes effect. A change that requires your express agreement under applicable law will apply to you only if you agree. Updates do not reduce your mandatory rights or the protections in our Data Processing Addendum and its Standard Contractual Clauses.
