Terms of Service

Effective and last updated: November 9, 2026

Important: arbitration, class waiver, liability limits

PLEASE READ THESE TERMS CAREFULLY. THEY CONTAIN A BINDING INDIVIDUAL ARBITRATION CLAUSE, A CLASS ACTION AND JURY TRIAL WAIVER, A RELEASE OF CLAIMS, A US$100 LIMIT ON LIABILITY, AND A ONE-YEAR DEADLINE FOR CLAIMS. THEY AFFECT YOUR LEGAL RIGHTS.

You must send us a written Notice of Dispute and wait 60 days before starting any claim (section 18).
Disputes are decided by one arbitrator through the American Arbitration Association, one person at a time, with no judge, jury or class action (section 18).
You can opt out of arbitration within 30 days of first accepting these Terms by emailing [email protected] with the subject "Arbitration opt-out" (section 18).
Diduno is free. The total liability of everyone who runs or helps Diduno is limited to US$100 (section 15).
You release the Diduno Parties from claims about other users, meetups, offers and third parties (section 15).
You meet other people and use offers at your own risk (section 9).
Claims must be started within one year (section 18).
Nothing here limits rights the law does not let us limit (section 20).

1. Agreement and definitions

These Terms are a contract between you and Diduno, an unincorporated student project run by its founders ("Diduno", "we", "us"). By signing in to Diduno you accept these Terms and our [Privacy Policy](/privacy) by ticking the agreement box on the sign-in screen, which links to both, mentions the arbitration clause and asks you to confirm you are 18 or older. We record the version you accepted and the time. Accounts created before this version was published are asked to accept it the next time they use Diduno. The text of every version stays available at /terms/archive. If you only browse as a guest, you are not asked to accept section 18 and the arbitration clause does not apply to you, but the other sections are the rules for using the site, your use is subject to them, and any court dispute with a guest is governed by the law and venue in section 17 and section 18. If you do not agree with these Terms, do not use Diduno.

Service: the Diduno website and web app, including the perk list, Campus Map, Live finds, Forum, favorites, calendar export and chat features.
You: anyone who visits or uses the Service.
Account: your profile, created by signing in with a school Microsoft account.
Your content: finds, Forum posts, replies, votes, corrections, chat messages, your profile and picture, and anything else you submit.
Third-party offers: perks, discounts, events, places and meetups listed or linked on the Service.
Diduno Parties: Diduno; its founders, owners, operators, organizers, contributors, volunteers, moderators and administrators; anyone affiliated with or helping run Diduno; any future company, LLC or successor that takes over Diduno; and each of their heirs, successors, assigns and agents. Every protection in these Terms (including the disclaimers, release, liability limits, indemnity, arbitration and dispute provisions) benefits each Diduno Party as an intended third-party beneficiary who may enforce it, and a claim against any Diduno Party is treated as a claim against Diduno under these Terms.
Succession: Diduno may assign or transfer the Service, these Terms and its data to a future entity (for example an LLC or corporation) by posting an update. The same promises then bind that entity.

2. Who may use Diduno

You must be at least 18 years old and located in the United States. You can browse without an account. To sign in you need a valid Microsoft account issued by a school we support, and you must be authorized to use it. If you use Diduno for an organization, you confirm you can bind it.

3. Independent project

Diduno is an independent student project that started at the Fall 2026 Temple AI Build challenge. It is not affiliated with, sponsored by, endorsed by or operated by Temple University or any other school, Microsoft, GroupMe, Vercel, OpenStreetMap or any offer provider or brand listed. Names and marks belong to their owners and appear only to identify offers. Diduno claims no trademark rights in third-party artwork (see the credits page).

4. Accounts

You must give true information and keep your account to yourself. You are responsible for everything done under your account. Do not create more than one account or use someone else's. Tell us at [email protected] if you think someone else is using your account. We may refuse or end access if your school account is not eligible.

5. What Diduno is

Diduno is a free guide to cheap, discounted and free offers, places, events and student posts. We collect most listings from public sources, automated collection and other students. We are not a seller, an agent, or a party to anything between you and an offer provider or another student. We do not provide, sell or guarantee any offer. Your dealings with merchants, schools, other students or any third party are solely between you and them. Links to third-party sites are for convenience; we do not control or endorse them.

Accuracy. Listings are gathered automatically from public sources and may be wrong, outdated, incomplete or no longer available. Prices, eligibility, hours, dates, locations and links can change at any time. Always check the official source before you rely on a listing or spend money. We are not liable for any loss caused by relying on one.

Fees. Diduno is free. We do not charge, show ads or sell your data today. There are no subscriptions or automatic renewals, so there is nothing to cancel or renew. We may change this by posting an update under section 19. Third parties you deal with may charge you.

6. Your content and our licence

You keep ownership of your content.
You give us a worldwide, non-exclusive, royalty-free, sublicensable licence to host, store, copy, display, reformat, distribute and publish your content in and through Diduno, and to use it to run, secure and improve Diduno. This includes the public calendar feed and, in a limited form, messages relayed to GroupMe, where GroupMe's terms also apply. Content on the Live map or Forum is visible to other signed-in students, and to the public where we make it public.
You give other users the right to view your content within the Service.
The licence lasts while your content is on Diduno and for a reasonable time after for backups and cached copies. It ends for the live Service when you delete the content or your account, except where others have already copied it or the law requires us to keep it.
You promise that you own your content or have the right to post it, that it is accurate, and that it does not break these Terms, any law or anyone's rights.
Feedback you give us may be used by us without obligation to you.

7. Acceptable use

You will not: break the law; harass or threaten anyone; post other people's personal information; spam or scam; impersonate anyone; upload malware; access another person's account; scrape, crawl, harvest or use bots or other automated means to access Diduno (except standard search engine indexing) without our written permission; overload or probe Diduno, or bypass its security, authentication, bans or rate limits; reverse engineer or copy Diduno except as the law allows; use Diduno for commercial advertising or resale; use Diduno in breach of a third party's terms (including Microsoft, GroupMe and OpenStreetMap-based services); or help anyone do these things. The community rules in section 8 apply as well.

8. Community rules

Share finds you saw yourself, at the place you pin, for as long as they last.
Say honestly what something costs. If you aren't sure, say so.
End your find or close your post when it's gone or claimed.

Not allowed

Harassment, hate, threats, or posting someone else's personal information.
Spam, scams, ads for your business, or links to phishing or malware.
Selling anything illegal, prescription drugs, alcohol to minors, weapons, or tickets above face value.
Sexual content, and anything that breaks Temple's student code of conduct or the law.
Pretending to be someone else, or a Temple office.
Anything discriminatory, violent or that targets a person; fake or misleading finds, offers or reports; false claims about prices or availability.
Counterfeit or stolen goods; referral codes or solicitations (links are blocked in chat, finds and posts).
Content that infringes anyone's intellectual property or privacy, and anything meant to harm, disrupt or overload Diduno.

Flags and bans

Flag anything that breaks these rules. Enough flags hide it until a moderator reviews it. Moderators can remove posts and finds and ban accounts, and a ban follows your school account (your Microsoft identity and school email). We use user flags, votes and manual review. Content may be hidden or removed, and accounts warned or banned, at our discretion, with or without notice.

Meet safely

Pick up giveaways and meet other students in public places on campus. Do not pin or share your home address or room. Diduno doesn't check posts before they appear and isn't part of any trade between students. See section 9.

About the information here

Perks, places and events come from public sources and change often. Always confirm the price and who qualifies on the official page before you sign up or go. Diduno is an independent student project, not affiliated with or endorsed by Temple University.

9. Safety, meetups and other students

Safety when meeting people. Meeting someone you do not know carries real risk. Diduno does not know who people are, does not supervise meetups and is not there. Meet only in public, well-lit places, tell someone where you are going, never go alone to a private place, and leave if you feel unsafe. Do not post or pin your home address or room. You choose whether to meet anyone, and you do so at your own risk.

Offers, places, events, links and posts on Diduno come from third parties or other users. We do not endorse, verify or guarantee any of them, and we are not responsible for them. We do not run background checks and do not screen posts before they appear, so we cannot verify what people post.

Use your own judgment. Meet in public, well-lit places, tell someone where you are going, and leave if you feel unsafe.
Do not give out financial details, passwords or other sensitive information.
Be careful with food, goods or items offered by others. We do not inspect them and make no promise about their safety, quality, allergens or legality.
Finds and posts may be wrong, expired or already gone. Do not travel only because of one.
In an emergency call 911 or campus safety. Report abuse to [email protected].
Meeting people, collecting food or goods, or going to places is at your own risk. To the extent the law allows, you knowingly and voluntarily assume all risks of doing so, including the risk of injury, illness, theft, harassment, property damage and death, whether or not foreseeable, and you are solely responsible for your interactions with other users. See also the release in section 15.

10. Our role in user content

Diduno is an interactive computer service (47 U.S.C. 230). We host content posted by users, and the law treats us as neither its publisher nor its speaker. Listings, descriptions and place information that we gather or write ourselves are ours and carry the accuracy disclaimers in section 5. We may, but are not required to, review, hide or remove content and suspend accounts, at our discretion and without notice.

Intimate images. If an intimate image of you was posted without your consent (including a computer-made one), email [email protected] with the page address and the subject "Image removal". We will remove it promptly after a valid request, and in any case within the time the federal TAKE IT DOWN Act requires, and look for copies on Diduno. We aim to check [email protected] every day and commit to remove a valid intimate-image report within 48 hours.

11. Our intellectual property

Diduno's software, design, compilation of offers, and the Diduno name and logo are owned by us or our licensors. We give you a limited, revocable, non-transferable licence to use Diduno for personal, non-commercial use. All rights not granted are reserved. Third-party names, logos and data belong to their owners. Map data is from OpenStreetMap contributors and OpenFreeMap. Other credits are on the credits page.

12. Copyright and takedowns

We respond to notices of copyright infringement under the Digital Millennium Copyright Act (17 U.S.C. 512). To report infringing content, or to dispute a removal, follow the process at /dmca. Our designated agent is the Diduno Copyright Agent, email [email protected]. We may remove content and end the accounts of repeat infringers.

13. Termination

You may stop using Diduno or delete your account in Settings at any time. We may suspend, restrict or end your access, remove content, or ban your account at any time, for any reason or no reason, without notice or liability. Reasons include breach of these Terms or the community rules, risk to others or to Diduno, legal requirements, or ending or changing the service. A ban follows your school account. After termination, sections that by nature should continue will continue, including 6 (licence for backups, copies and content already shared), 9 to 12 and 14 to 20. Some moderation records are kept as described in the Privacy Policy.

14. Disclaimer of warranties

DIDUNO, ALL CONTENT AND ALL THIRD-PARTY OFFERS ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AVAILABILITY AND SECURITY. WE DO NOT PROMISE THAT DIDUNO WILL BE UNINTERRUPTED, ERROR-FREE, SECURE OR FREE OF HARMFUL COMPONENTS, OR THAT ANY OFFER, FIND, POST, LISTING, PRICE, EVENT, PLACE, LOCATION OR USER IS ACCURATE, CURRENT, AS DESCRIBED OR SAFE. WE DO NOT ENDORSE ANY OFFER, PROVIDER OR USER. Nothing on Diduno is legal, financial, medical or other professional advice. Some places do not allow some of these exclusions, so they may not apply to you in full; then they apply to the extent the law permits. See also the Disclaimer.

15. Limitation of liability and release

TO THE MAXIMUM EXTENT THE LAW ALLOWS:

Cap. THE TOTAL LIABILITY OF ALL DIDUNO PARTIES TOGETHER FOR ALL CLAIMS OF ANY KIND RELATED TO DIDUNO WILL NOT EXCEED ONE HUNDRED US DOLLARS (US$100). Diduno is free, so this is the most we can fairly be expected to owe. The cap applies to every legal theory, including contract, tort (including negligence), statute and strict liability.
No indirect damages. NO DIDUNO PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, GOODWILL OR OPPORTUNITIES, EVEN IF TOLD THEY COULD HAPPEN.
Other users and third parties. NO DIDUNO PARTY IS LIABLE FOR THE CONDUCT OF ANY USER OR THIRD PARTY, FOR USER CONTENT, OR FOR ANY PERSONAL INJURY, ILLNESS, DEATH, PROPERTY DAMAGE, THEFT OR OTHER LOSS ARISING FROM OFFERS, EVENTS, PLACES, MEETUPS, FOOD, GOODS, SAFETY INCIDENTS OR OTHER USERS.
Release. YOU RELEASE THE DIDUNO PARTIES FROM ALL CLAIMS, DEMANDS AND DAMAGES, KNOWN OR UNKNOWN, ARISING FROM OTHER USERS' CONDUCT, MEETUPS, OFFERS, THIRD PARTIES AND CONTENT, INCLUDING CLAIMS BASED ON THE ORDINARY NEGLIGENCE OF A DIDUNO PARTY, TO THE EXTENT PENNSYLVANIA LAW PERMITS. If you live in California, you waive California Civil Code section 1542, which says: a general release does not extend to claims the creditor or releasing party does not know or suspect to exist in their favor at the time of executing the release and that, if known, would have materially affected the settlement. You waive similar laws of any other state.
Independent limits. Each limit in this section is separate and survives even if another limit fails of its essential purpose.
What is not limited. This section does not limit liability for gross negligence or willful misconduct to the extent the law does not allow that, or any other liability the law does not allow to be limited.

16. Indemnity

You will defend, indemnify and hold harmless every Diduno Party from claims, losses, damages, liabilities, fines, penalties, settlements, costs and attorney's fees arising from your content, your conduct, your breach of these Terms or the community rules, your violation of law or anyone's rights, or a dispute between you and another user. We may take over the defense of any matter at your cost. This does not apply to the extent a claim is caused by a Diduno Party's own gross negligence or willful misconduct.

17. Governing law and venue

Pennsylvania law governs these Terms and all disputes about Diduno, without regard to conflict-of-laws rules, except that the Federal Arbitration Act governs section 18. For anything that is not arbitrated, you and we submit to the exclusive jurisdiction of the state courts in Philadelphia County, Pennsylvania, or the U.S. District Court for the Eastern District of Pennsylvania, and you waive any objection to that venue or that it is an inconvenient forum.

18. Disputes: notice, arbitration and class action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO GO TO COURT AND TO HAVE A JURY. In this section "dispute" means any claim or disagreement between you and any Diduno Party arising out of or relating to these Terms or Diduno, whenever it arose.

Step 1: Notice of Dispute and 60 days to resolve. Before starting any arbitration or court case, you must send a written Notice of Dispute by email to [email protected] (and by mail to the postal address we will give within 5 business days of an emailed request). It must include your name and account email, the facts, the specific relief and amount you seek, and your personal signature. For 60 days after we receive a complete notice the parties will try in good faith to resolve it, and no one may file a case until that period ends. The time limit in this section is paused during those 60 days. We may send you a notice the same way. We do not accept service of process by email unless we confirm in writing.
Step 2: Binding individual arbitration. Except for the exceptions below, any dispute will be resolved by final and binding individual arbitration, not in court, with no judge or jury. The American Arbitration Association (AAA) will run it under its Consumer Arbitration Rules, available at adr.org, before one arbitrator. It will be by video or on documents unless the arbitrator finds a live hearing necessary. The arbitrator applies the law and may award only the individual relief a court could. Diduno pays the AAA filing, administrative and arbitrator fees to the extent the AAA Consumer Fee Schedule assigns them to the business. Each side bears its own lawyers and experts, except as the AAA rules or law require or as section 18 says below. The arbitrator decides questions of arbitrability and enforceability, except that a court decides whether the class waiver and the batching rule apply. The award is final, and judgment may be entered in any court with jurisdiction. To the extent the law allows, the arbitration is confidential.
Class, group and jury waiver. TO THE EXTENT THE LAW ALLOWS, YOU AND WE MAY BRING CLAIMS ONLY ON AN INDIVIDUAL BASIS, AND NOT AS A PLAINTIFF OR MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED, REPRESENTATIVE OR PRIVATE-ATTORNEY-GENERAL ACTION. EACH OF US WAIVES THE RIGHT TO A JURY TRIAL. The arbitrator may not combine claims or award class-wide relief. If this waiver is found unenforceable as to a claim, that claim proceeds in court (not in arbitration) in the venue in section 17, without a jury, and the rest of this section still applies to all other claims.
Many similar claims. If 25 or more substantially similar claims are filed by the same lawyers or coordinated lawyers, they are handled in batches of at most 10 claims, starting with a test group of 5 chosen by each side. Fees are due only for the current batch, and the other claims are paused and their time limits tolled until their batch begins.
Exceptions. Either side may (a) bring an individual claim in small-claims court in Philadelphia County, or in your county of residence, if it qualifies and stays individual, (b) ask a court for an order to stop infringement or misuse of intellectual property or misuse of Diduno, and (c) bring claims the law does not allow to be arbitrated.
Opt out within 30 days. You may opt out of arbitration by emailing [email protected] from your account email within 30 days after you first accept these Terms, with the subject "Arbitration opt-out", your name and your account email. Opting out of arbitration does not opt you out of anything else in these Terms. If you opt out, disputes go to the courts in section 17.
One-year deadline. To the extent the law allows, any claim must be started (by sending a complete Notice of Dispute) within one year after it arose, or it is barred forever.
Fee shifting. If you start an arbitration or lawsuit on a claim that is subject to this section or released in section 15, or on a claim a tribunal finds frivolous or brought in bad faith, you will pay the Diduno Parties' reasonable attorney's fees and costs to the extent the law permits. The AAA rules on fees also apply.
Changes. If we change this section, the change does not apply to disputes already begun, and you may opt out of the changed section by emailing us within 30 days after we post it, in the same way as the opt-out above.
Survival and severability. This section survives termination. If any part of it other than the class waiver is found unenforceable, that part is removed and the rest stays in effect.

19. Changes to the service or these Terms

We may change, suspend or end any part of Diduno at any time. We may change these Terms by posting a new version with a new date. Material changes take effect 14 days after posting, or sooner if needed to follow the law or protect safety or security. If you keep using Diduno after a change, you accept the new Terms. If a change is material, we will ask you to accept the new version before you can keep using your account (you can decline and sign out), and each version stays available at /terms/archive. If you do not agree, stop using Diduno and delete your account. Changes do not apply to disputes already begun.

20. General

Whole agreement: these Terms and the Privacy Policy are the whole agreement between you and us about Diduno.
Severability: if a part is found unenforceable, the rest stays in effect, and that part is enforced to the maximum extent allowed.
No waiver: our not enforcing a right is not giving it up.
Assignment: you may not assign these Terms. Diduno may assign them, for example to a company that takes over Diduno.
No partnership: nothing here creates a partnership, employment or agency.
Events beyond our control: we are not liable for events beyond our reasonable control (force majeure).
Notices: we give notice by posting on Diduno. For a notice about your own account we may also write to the school email address on it. You give notice to us by email to [email protected].
United States only: Diduno is controlled from the United States and is not intended for use elsewhere. You must follow export control and sanctions laws.
Third parties: no one else has rights under these Terms, except the Diduno Parties.
Interpretation: headings are for convenience only, and these Terms are not read against us as the drafter.
Your legal rights: nothing in these Terms takes away rights you have under law that cannot be waived, and where a limit here is not allowed for you, it applies to the greatest extent the law permits.

21. Contact

Questions, reports, ban appeals, copyright notices, Notices of Dispute and other legal notices: [email protected] (our only mailbox). We aim to answer within 10 business days. We have no published postal address; we give one for formal notices within 5 business days of an emailed request. See the Privacy Policy for how we handle data, the Cookie and Storage Policy, Your Privacy Choices, the Disclaimer and the Accessibility Statement.
